units: drop dependency on systemd-remount-fs.service from systemd-pstore.service

This dependency is now generated automatically given we use
StateDirectory=. Moreover the combination of Wants= and After= was too
strong anyway, as whether remount-fs is pulled in or not should not be up
to systemd-pstore.service, and in fact is part of the initial
transaction anyway.
