[gnome-boxes] Add new SAVED MachineState

[Alexander Larsson <alexl src gnome org>]

commit 4f6f4214b7bba379174f0494c773d176f064d4cd

    Add new SAVED MachineState
    
    This way we can show a greyed out last screenshot in the collection
    view, rather than a completely black one. While restoring takes a
    while, the screenshot is typically what you will get back to when
    restored, so this makes more sense.
