Revert "Revert "fsck: add new -l switch to fsck mount options""

This reverts commit c8bc83f5ea.

As Karel pointed out the -l switch doesn't actualy conflict with
per-filesystem options, since those can be seperated by -- in the
command line. Since -l is here to stay we hence enable it again for now.
