Subject: [PATCH] test/udev-test.pl: suppress umount error message at startup

umount emits an error message "no mount point specified" if the
tmpfs isn't mounted yet, which is the normal case.
Suppress that by redirecting stderr.

(cherry picked from commit f1cb0860549e775be5f91237b5a3b97698dd14dd)
