this first time I see that someone has a pattern in fstab, it seems
undocumented and very probably unsupported on many places. But it
seems that old (non-libmount) supported this feature too.

This is hack ;-)
It would be better to improve mnt_context_apply_fstab() to initialize
cxt->fstype_pattern (see mnt_context_set_fstype_pattern()) and
zeroize cxt->fs->type if the fstab entry contains a pattern rather
than a real fstype.
