dagutil: remove heads() and localsubset from revlogdag.__init__

The previous commit removed the last consumer of this API.

I'm not going to mark as API incompatible because I doubt anybody
used this functionality (outside of possibly passing an argument
to revlogdag.__init__). I intend to remove revlogdag later in
this series and its API annotation will cover this one.
