selftests: always check mask returned by statmount(2)

STATMOUNT_MNT_OPTS can actually be missing if there are no options. This
is a change of behavior since 75ead69a7173 ("fs: don't let statmount return
empty strings").

The other checks shouldn't actually trigger, but add them for correctness
and for easier debugging if the test fails.
