rtsp vaapiparse_h264 not being used

[Spruyt, Randy]

H.264 webcam is sending an RTSP H.264 byte-stream with NAL alignment. I'd expect the playbin to use the vaapiparse_h264 element to turn this into a format the decoder can use, but we get this. The vaapiparse_h264 element works fine, as does the vaapidecode, h264parse and avdec_h264, etc.
