lfs: register the flag processors per repository

Previously, enabling the extension for any repo in commandserver or hgweb would
enable the flags on all repos.  Since localrepo.resolverevlogstorevfsoptions()
is called so early, the check to see if the extension is enabled on the repo
(which hasn't been instantiated yet) is a bit awkward.  But I don't see a better
way.
