waylandsink: call gst_video_sink_center_rect with a destination rectangle that starts from (0,0)

Browse source 
The intention of this code is to find the center rectangle relative
to (0,0), since subsurface coordinates are relative to the parent
surface.

The old code used to work but was wrong and broken by
