[PATCH 5.15 033/196] selftests: skip mincore.check_file_mmap when fs lacks needed support

[Greg Kroah-Hartman]

From: Cristian Marussi <cristian.marussi@xxxxxxx>

[ Upstream commit dae1d8ac31896988e7313384c0370176a75e9b45 ]

Report mincore.check_file_mmap as SKIP instead of FAIL if the underlying
filesystem lacks support of O_TMPFILE or fallocate since such failures
are not really related to mincore functionality.
