selftests/mm: skip mlock tests if nobody user can't read it
If running from a directory that can't be read by unprivileged users,
executing on-fault-test via the nobody user will fail.
The kselftest build does give the file the correct permissions, but after
being installed it might be in a directory without global execute
permissions.
Since the script can't safely fix that, just skip if it happens. Note
that the stderr of the `ls` command is unfiltered meaning the user sees a
"permission denied" error that can help inform them why the test was
skipped.
