[mutter] meta-background-actor: Rename brightness to vignette_brightness

[Alessandro Bono <abono src gnome org>]

commit cbc4563b30d081a4c77445baf60dc15cd076031d

    meta-background-actor: Rename brightness to vignette_brightness
    
    The brightness is about the vignette. Add a 'vignette_' prefix in order
    to give more context. Keep the property name as it is, doing so we don't
    break any plugin (e.g., gnome-shell).
