Add shellcheck source directive to prevent old versions of shellcheck to
issue warning SC1090 for perf shell scripts, e.g.:
In tests/shell/base_probe/test_line_semantics.sh line 20:
. "$DIR_PATH/../common/init.sh"
^---------------------------^ SC1090: Can't follow non-constant source. Use a directive to specify location.
shellcheck versions since 0.7.2 handle such dynamic source includes in a
more friendly manner [1]; older versions show the warning and thus
break the perf build unless NO_SHELLCHECK is set to '1'.
Fixes: 241f21be7d0f ("perf test perftool_testsuite: Use absolute paths")

Changes in v2:
* Extend commit message and mention affected shellcheck versions
(< 0.7.2)
* Link to v1: https://lore.kernel.org/r/20251229-perf-add-shellcheck-sc1090-annotation-v1-1-083821aeefa6@avm.de

Another way w/o new shellcheck directives would be to update the minimum
shellcheck version in tools/perf/Makefile.perf to 0.7.2. I'll send
that as an alternative patch.
Newer versions of shellcheck are available since e.g.
Debian bookworm 12 (released: 2023/06), Ubuntu jammy 22.04 (released:
2022/04), Fedora 37 (released: 2022/11)

Thanks for doing this, I think that's much simpler than this.

I'm not sure how shellcheck handles the source directory, but I think we
used to assume it's the directory where the current script is on.
Something like:
# shellcheck source=../common/init.sh
But as I said, it'd be better to increase the minimal shellcheck version
if it can handle that automatically.
Thanks,
Namhyung
