selftests/bpf: Skip perf hw events test if the setup disabled it

Browse source

commit f1c3656c6d upstream.

The same with commit 4e59afbbed ("selftests/bpf: skip nmi test when perf
hw events are disabled"), it would make more sense to skip the
test_stacktrace_build_id_nmi test if the setup (e.g. virtual machines) has
disabled hardware perf events.

Fixes: 13790d1cc7 ("bpf: add selftest for stackmap with build_id in NMI context")
