[PATCH bpf-next] selftests/bpf: Add selftest deny_namespace to s390x deny list

[PATCH bpf-next] selftests/bpf: Add selftest deny_namespace to s390x deny list

[Yonghong Song]

BPF CI reported that selftest deny_namespace failed with s390x.

  test_unpriv_userns_create_no_bpf:PASS:no-bpf unpriv new user ns 0 nsec
  test_deny_namespace:PASS:skel load 0 nsec
  libbpf: prog 'test_userns_create': failed to attach: ERROR: strerror_r(-524)=22
  libbpf: prog 'test_userns_create': failed to auto-attach: -524
  test_deny_namespace:FAIL:attach unexpected error: -524 (errno 524)
  #57/1    deny_namespace/unpriv_userns_create_no_bpf:FAIL
  #57      deny_namespace:FAIL

BPF program test_userns_create is a BPF LSM type program which is
based on trampoline and s390x does not support s390x. Let add the
test to x390x deny list to avoid this failure in BPF CI.
