largefiles: pass a matcher instead of a raw file list to removelargefiles()

This is consistent with addlargefiles(), and will make it easier to get the
paths that are printed correct when recursing into subrepos or invoking from
outside the repository.  It also now restricts the path that the addremove is
performed on, as is done with normal files.

The status call needs to exclude clean files when performing an addremove
because the addremove override method calling this used to pass the list of
files to delete, which caused the matcher to only consider those files in
building the status list.  There's no reason for addremove to care about clean
files anyway- we don't want them deleted.
