GstVaapiPixmap is an abstract base class which only implementation were GstVaapiPixmapX11. This class were used for a special type of rendering in the tests apps, utterly unrelated in GStreamer. Since gstreamer-vaapi is no longer a general-user wrapper for VA-API we should remove this unused API. This removal drops libxrender dependency.
