perf tests: Fix test_arm_callgraph_fp variable expansion
$TEST_PROGRAM is a command with spaces so it's supposed to be word split. The referenced fix to fix the shellcheck warnings incorrectly quoted this string so unquote it to fix the test.
At the same time silence the shellcheck warning for that line and fix two more shellcheck errors at the end of the script.

perf tests arm_callgraph_fp: Address shellcheck warnings about signal names and adding double quotes for expression
Running shellcheck -S on test_arm_calligraph_fp throws warnings SC2086 and SC3049,
$shellcheck -S warning tests/shell/test_arm_callgraph_fp.sh rm -f $PERF_DATA : Double quote to prevent globbing and word splitting. trap cleanup_files exit term int : In POSIX sh, using lower/mixed case for signal names is undefined.
After fixing the warnings,
$shellcheck tests/shell/test_arm_callgraph_fp.sh $ echo $? 0
To address the POSIX shell warnings added changes to convert Lowercase signal names to uppercase in the script and double quoted the command substitutions($fix to "$fix") to solve Globbing warnings.

perf test: Record only user callchains on the "Check Arm64 callgraphs are complete in fp mode" test
The testcase 'Check Arm64 callgraphs are complete in fp mode' wants to see the following output:
perf test: Record only user callchains on the "Check Arm64 callgraphs are complete in fp mode" test
The testcase 'Check Arm64 callgraphs are complete in fp mode' wants to see the following output:
610 leaf 62f parent 648 main
However, without excluding kernel callchains, the output might look like:
ffffc2ff40ef1b5c arch_local_irq_enable ffffc2ff419d032c __schedule ffffc2ff419d06c0 schedule ffffc2ff40e4da30 do_notify_resume ffffc2ff40e421b0 work_pending 610 leaf 62f parent 648 main
Adding '--user-callchains' leaves only the wanted symbols in the chain.

It's supposed to work with both unwinders:
| $ make # for libunwind (default) | $ make NO_LIBUNWIND=1 # for libdw
Tester notes:
Ran it on N1SDP and it passes, and it fails if b9f6fbb3b2c29736 ("perf arm64: Inject missing frames when using 'perf record --call-graph=fp'") isn't applied.
