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.

/*

* ARM requires explicit rounding down of the instruction pointer in Thumb mode,
