Jeremy Linton 45fa7c3869 perf tests: Fix coresight perf test failure. 
Currently the `perf test` always fails the coresight test like:

  89: Check Arm CoreSight trace data recording and synthesized samples: FAILED!

That is because the test_arm_coresight.sh is attempting to SIGINT the
parent but is using $$ rather than $PPID and it sigint's itself when
run under the perf test framework.

Since this is done in a trap clause it ends up returning a non zero
return.

Since $PPID is a bash ism and not all distros are linking /bin/sh to
bash, the alternative parent pid lookups are uglier than just dropping
the kill, and its not strictly needed, lets pick the simple solution and
drop the sigint.

Fixes: 133fe2e617 ("perf tests: Improve temp file cleanup in test_arm_coresight.sh")
