[PATCH AUTOSEL 4.19 103/192] selftests: skip seccomp get_metadata test if not real root

Note that I used XFAIL here because that's what the test does later if CONFIG_CHEKCKPOINT_RESTORE happens to not be enabled.

[PATCH AUTOSEL 5.0 172/262] bpf: test_maps: fix possible out of bound access warning
