    backend: Get the default seat directly
    
    In various places we retrieved the default seat from the ClutterBackend.
    All the clutter backends implement this by calling
    meta_backend_get_default_seat() which will then return
    MetaBackendPrivate::default_seat.
    
    Lets avoid this by fetching the default seat directly.
