wayland: Flatten data source object hierarchy

Browse source 
We have an abstract MetaWaylandDataSource and 2 subclasses for
clipboard/primary data sources. Since the abstraction provided
by the additional sublevel is arguable, push the wl_resource
field up, and leave us with just 2 objects to think about, all
of them containing a wl_resource.
