layout: focus a window that goes fullscreen over the focused one

A client turning fullscreen on itself, over xdg or X11, left keyboard focus on a window it now covered, which is invisible but still typed into. Layout::focus_if_covering moves focus to it unless the focused window is its own transient, so a dialog stays usable.
