perf tests shell: Fixed shellcheck warnings
Fixed the shellcheck warnings in buildid.sh, record+probe_libc_inet_pton.sh and record+script_probe_vfs_getname.sh perf shell scripts:
1. Prefer [ p ] && [ q ] as [ p -a q ] is not well defined. 2. Prefer [ p ] || [ q ] as [ p -o q ] is not well defined. 3. Used * argument to avoid the argument mixes string and array 4. Resolved issue for variable refernce, where the variable is being used before it has been initialized. 5. Resolved word splitting issue (syntax error). 6. The "err" variable has been removed from buildid.sh since it is not used anywhere in the code.

perf test buildid: Fix shell string substitutions
The perf test named “build id cache operations” skips with below error on some distros:
<<>> 78: build id cache operations : test child forked, pid 111101 WARNING: wine not found. PE binaries will not be run. test binaries: /tmp/perf.ex.SHA1.PKz /tmp/perf.ex.MD5.Gt3 ./tests/shell/../pe-file.exe DEBUGINFOD_URLS= Adding 4abd406f041feb4f10ecde3fc30fd0639e1a91cb /tmp/perf.ex.SHA1.PKz: Ok build id: 4abd406f041feb4f10ecde3fc30fd0639e1a91cb ./tests/shell/buildid.sh: 69: ./tests/shell/buildid.sh: Bad substitution test child finished with -2 build id cache operations: Skip <<>>
The test script "tests/shell/buildid.sh" uses some of the string substitution ways which are supported in bash, but not in "sh" or other shells. Above error on line number 69 that reports "Bad substitution" is:
<<>> link=${build_id_dir}/.build-id/${id:0:2}/${id:2} <<>>
Here the way of getting first two characters from id ie, ${id:0:2} and similarly expressions like ${id:2} is not recognised in "sh". So the line errors and instead of hitting failure, the test gets skipped as shown in logs. So the syntax issue causes test not to be executed in such cases. Similarly usage : "${@: -1}" [ to pick last argument passed to a function] in “test_record” doesn’t work in all distros.
Fix this by using alternative way with shell substitution to pick required characters from the string. Also fix the usage of “${@: -1}” to work in all cases.
Another usage in “test_record” is:
<<>> ${perf} record --buildid-all -o ${data} $@ &> ${log} <<>>
This causes the 'perf record' to start in background and Results in the data file not being created by the time "check" function is invoked. Below log shows 'perf record' result getting displayed after the call to "check" function.

perf test build-id: Fix test check for PE file
Perf test "build id cache operations" fails for PE executable. Logs below from powerpc system. Same is observed on x86 as well.
<<>> Adding 5a0fd882b53084224ba47b624c55a469 ./tests/shell/../pe-file.exe: Ok build id: 5a0fd882b53084224ba47b624c55a469 link: /tmp/perf.debug.w0V/.build-id/5a/0fd882b53084224ba47b624c55a469 file: /tmp/perf.debug.w0V/.build-id/5a/../../root/<user>/linux/tools/perf/tests/pe-file.exe/5a0fd882b53084224ba47b624c55a469/elf failed: file /tmp/perf.debug.w0V/.build-id/5a/../../root/<user>/linux/tools/perf/tests/pe-file.exe/5a0fd882b53084224ba47b624c55a469/elf does not exist test child finished with -1 ---- end ---- build id cache operations: FAILED! <<>>
The test tries to do:
<<>> mkdir /tmp/perf.debug.TeY1 perf --buildid-dir /tmp/perf.debug.TeY1 buildid-cache -v -a ./tests/shell/../pe-file.exe <<>>
The option "--buildid-dir" sets the build id cache directory as /tmp/perf.debug.TeY1. The option given to buildid-cahe, ie "-a ./tests/shell/../pe-file.exe", is to add the pe-file.exe to the cache.
The testcase, sets buildid-dir and adds the file: pe-file.exe to build id cache. To check if the command is run successfully, "check" function looks for presence of the file in buildid cache directory. But the check here expects the added file to be executable. Snippet below:
<<>> if [ ! -x $file ]; then echo "failed: file ${file} does not exist" exit 1 fi <<>>
The buildid test is done for sha1 binary, md5 binary and also for PE file. The first two binaries are created at runtime by compiling with "--build-id" option and hence the check for sha1/md5 test should use [ ! -x ]. But in case of PE file, the permission for this input file is rw-r--r-- Hence the file added to build id cache has same permissoin
Original file:
ls tests/pe-file.exe | xargs stat --printf "%n %A \n" tests/pe-file.exe -rw-r--r--
buildid cache file:
ls /tmp/perf.debug.w0V/.build-id/5a/../../root/<user>/linux/tools/perf/tests/pe-file.exe/5a0fd882b53084224ba47b624c55a469/elf | xargs stat --printf "%n %A \n" /tmp/perf.debug.w0V/.build-id/5a/../../root/<user>/linux/tools/perf/tests/pe-file.exe/5a0fd882b53084224ba47b624c55a469/elf -rw-r--r--
Fix the test to match with the permission of original file in case of FE file. ie if the "tests/pe-file.exe" file is not having exec permission, just check for existence of the buildid file using [ ! -e <file> ]

perf buildid-cache: Add test for PE executable
This builds on the previous changes to tests/shell/buildid.sh, adding tests for a PE file. It adds it to the build-id cache manually and, if Wine is available, runs it under "perf record" and verifies that it was added automatically.
If wine is not installed, only warnings are printed; the test can still exit 0.
