selftests/bpf: Add a test to verify previous stacksafe() fix
commit 662c3e2db00f92e50c26e9dc4fe47c52223d9982 upstream.
A selftest is added such that without the previous patch,
a crash can happen. With the previous patch, the test can
run successfully. The new test is written in a way which
mimics original crash case:
main_prog
static_prog_1
static_prog_2
where static_prog_1 has different paths to static_prog_2
and some path has stack allocated and some other path
does not. A stacksafe() checking in static_prog_2()
triggered the crash.
