widget: Only include visible actors in focus chain

Browse Source 
It isn't useful to move the keyboard focus to a hidden actor, so
only include visible actors in the focus chain - this is in fact
the documented behavior of st_widget_get_focus_chain(), so having
the default implementation return all children has always been
unexpected.
