layout: send signal when content is set to bg

Summary:
 - elm.swallow.background is a part reserved for customized bg.
 - When default bg image is already set, default bg has to be hidden when customized bg is set.
 - Emitting signal when a content is set to this part makes this hiding process a lot easier.
