clutter/bin-layout: Remove custom alignment properties

Browse Source 
The layout manager takes the generic ClutterActor expand/align
properties into account. Everyone should already use those instead
of the custom layout/child properties, so removing them should have
little fallout, while making for a nice cleanup.
