Dmitrii Dolgov e02feb3f1f selftests/bpf: Test re-attachment fix for bpf_tracing_prog_attach
Add a test case to verify the fix for "prog->aux->dst_trampoline and
tgt_prog is NULL" branch in bpf_tracing_prog_attach. The sequence of
events:

1. load rawtp program
2. load fentry program with rawtp as target_fd
3. create tracing link for fentry program with target_fd = 0
4. repeat 3
