units: local-fs.target - don't pull in default dependencies

Reported by Gerardo Exequiel Pozzi:

Looks like [commit a4a878d0] also changes a unrelated file
(units/local-fs.target) [partially]reverting the commit
40f862e3 (filesystem targets: disable default dependencies)

The side effect, at least in my case is that the "nofail" option in both
"crypttab" and "fstab" has partial effect does the default timeout
instead of continue normal boot without timeout.
