selftests/bpf: Add stacktrace ips test for fentry/fexit
...
Adding test that attaches fentry/fexitand verifies the
ORC stacktrace matches expected functions.
The test is only for ORC unwinder to keep it simple.

selftests/bpf: Add stacktrace ips test for kprobe_multi/kretprobe_multi
...
Adding test that attaches kprobe/kretprobe multi and verifies the
ORC stacktrace matches expected functions.
Adding bpf_testmod_stacktrace_test function to bpf_testmod kernel
module which is called through several functions so we get reliable
call path for stacktrace.
The test is only for ORC unwinder to keep it simple.
