[ Upstream commit 8206e4e95230daeeba43c59fc7c39656883ecd62 ]
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.
