[PATCH bpf] selftests/bpf: Add lru_bug to s390x deny list

[Daniel Müller]

The lru_bug BPF selftest is failing execution on s390x machines. The
failure is due to program attachment failing in turn, similar to a bunch
of other tests. Those other tests have already been deny-listed and with
this change we do the same for the lru_bug test, adding it to the
corresponding file.

Thanks Daniel for fixing this quickly. It should recover: https://github.com/kernel-patches/bpf/runs/7772305011?check_suite_focus=true
