hi,
Mahe reported missing function from stack trace on top of kprobe multi
program. It turned out the latest fix [1] needs some more fixing.

v2 changes:
- keep the unwind same as for kprobes, attached function
  is part of entry probe stacktrace, not kretprobe [Steven]
- several change in trigger bench [Andrii]
- added selftests for standard kprobes and fentry/fexit probes [Andrii]
