waylandsink: set video surface opaque
Unless the video format has an alpha component (ARGB, ...), set the
video_surface opaque.
In the usual case where the black area_surface has the same size as the
video_surface (eg: run gst-play-1.0 video.mp4), this makes the black
surface totally occluded which makes weston compositor's life easier
since it can ignore that surface.
Also unconditionally set the black area_surface opaque.
