[banshee] build: if Gst# backend is enabled, don't build the unmanaged backend

    build: if Gst# backend is enabled, don't build the unmanaged backend
    
    It could happen that both backends are built, and the user thinks it is
    running only the GStreamerSharp backend, when in reality it could be
    running both at the same time.
