Revert "vo_dmabuf_wayland: assume counter-clockwise rotations" 

This commit was originally sparked by a change in sway. When looking at
the wording of the spec, it was believed that the rotation should be
counter-clockwise. But that was interpreted incorrectly. The rotation
direction in the spec is meant for compositors not clients. Clients
should be rotating clockwise and compositors rotate it the opposite
direction. Also see the discussion in upstream wayland*.
