cluster-receiver: just RRECOMMEND gstreamer-vaapi for Intel
The gstreamer-vaapi plugin is not available / buildable on all non-Intel
platforms, so to avoid issues just RRECOMMEND it when building for
Intel, as the gstreamer pipeline construction code in the application
checks for its presence at runtime already.
