perf tests record_offcpu: Fix shellcheck warnings about word splitting/quoting and signal names case
Running shellcheck on record_offcpu.sh throws below warning:

In tests/shell/record_offcpu.sh line 25:

^-----^ SC2046 (warning): Quote this to prevent word splitting.
Fixed the warnings by:
- Capitalize signals(INT, TERM, EXIT) to avoid mixed/lower case naming of
signals.
- Adding quotes to avoid word splitting.
Result from shellcheck after patch changes:
$ shellcheck -S warning record_offcpu.sh

Revert "perf build: Make BUILD_BPF_SKEL default, rename to NO_BPF_SKEL"
This reverts commit a980755beb5aca9002e1c95ba519b83a44242b5b.
We need to better polish building with BPF skels, so revert back to
making it an experimental feature that has to be explicitely enabled
using BUILD_BPF_SKEL=1.

perf build: Make BUILD_BPF_SKEL default, rename to NO_BPF_SKEL
BPF skeleton support is now key to a number of perf features. Rather
than making it so that BPF support must be enabled for the build, make
this the default and error if the build lacks a clang and libbpf that
are sufficient. To avoid the error and build without BPF skeletons the
NO_BPF_SKEL=1 flag can be used. Add a build-options flag to 'perf
version' to enable detection of the BPF skeleton support and use this
in the offcpu shell test.

perf tools: Use "grep -E" instead of "egrep"
The latest version of grep claims the egrep is now obsolete so the build
now contains warnings that look like:
egrep: warning: egrep is obsolescent; using grep -E
fix this up by moving the related file to use "grep -E" instead.
sed -i "s/egrep/grep -E/g" `grep egrep -rwl tools/perf`
Here are the steps to install the latest grep:
wget http://ftp.gnu.org/gnu/grep/grep-3.8.tar.gz
tar xf grep-3.8.tar.gz
cd grep-3.8 && ./configure && make
sudo make install
export PATH=/usr/local/bin:$PATH
