commit 6d74f64b922b8394dccc52576659cb0dc0a1da7b upstream.
There are a few fentry/fexit programs returning non-0.
The tests with these programs will break with the previous
patch which enfoced return-0 rules. Fix them properly.
Fixes: ac065870d928 ("selftests/bpf: Add BPF_PROG, BPF_KPROBE, and
BPF_KRETPROBE macros")
