    clutter/actor: Always reset absolute_origin_changed after relayout
    
    Since the introduction of the shallow relayout functionality it's
    possible to start an allocation cycle at any point in the tree, not only
    at the stage. Now when starting an allocation at an actor that's not the
    stage, we'd still look at the absolute_origin_changed property of this
    actors parent, which might still be set to TRUE from the parents last
    allocation.
    
    So avoid using the parents absolute_origin_changed property from the
    last allocation in case a shallow relayout is being done and always
    reset the absolute_origin_changed property to FALSE after the allocation
    cycle.
    
    This broke with the removal of the ABSOLUTE_ORIGIN_CHANGED
    ClutterAllocationFlag that was done in commit dc8e5c7f.
