Add grilo-plugins and tracker-miners dependencies
    
    One or both of these packages are used by some of GNOME's apps
    (Boxes, Games, Music, Photos, Rhythmbox, Totem) and have a number
    of dependencies (some of which are also used directly).
    
    Note that tracker-miners itself must not be included here.  Each flatpak
    must compile that themselves with their ID-specific domain ontology.
    Providing the dependencies here should make that simpler.
