largefiles: enable subrepo support for add

The --large, --normal and --lfsize args couldn't be passed to a subrepo before,
and files in the subrepos would be added silently (if -v wasn't specified) as
normal files.  As an added bonus, 'hg add --dry-run' no longer prints that
largefiles would also be added as normal files as well.
