gallium/targets: Add vdpau target for nouveau

Should fall back to shader based decoding (g3dvl) for now.

This is probably broken on systems that support xvmc, because
nouveau_video_buffer_create has no way to know for what api
the buffer is created, so I think this call might need a
separate argument as workaround.
