lfs: enable the extension locally after cloning a repo with 'lfs' requirement
We do the same thing on clone for the largefiles extension, as a convenience.
Similar to largefiles, it's probably safer to only enable this extension on a
per repo basis because it is trivial to add an lfs file. And that gives the
repository some centralized VCS characteristics.
