Marco Elver 5504f67944 perf test sigtrap: Add basic stress test for sigtrap handling ...

Add basic stress test for sigtrap handling as a perf tool built-in test.
This allows sanity checking the basic sigtrap functionality from within
the perf tool.

Committer notes:

Reported that !root was getting -EPERM, applied a fixup from Marco to
set .exclude_{hv,kernel} that made it work.
