largefiles: notice dirty large files in a subrepo

Summary and commit use dirty() to check the status of a subrepository,
so this overrides dirty() in the subrepo in the same manner as
status() to check the large files instead of their standins.

Previously, if only a large file was changed in a subrepo, summary in
the top level repo would not report the subrepo was dirty and commit
-S would report nothing changed.  If any type of file was changed in
the top repo and only a large file in the subrepo, commit -S would not
commit the changes to the subrepo.
