selftests: skip mincore.check_file_mmap when fs lacks needed support

BugLink: https://bugs.launchpad.net/bugs/1963890
[ 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.
