windowManager: Only allow top-drag gesture if focus window is fullscreen

The top drag gesture is not of any use if the topmost window is not
a fullscreen window and will only block events near the important top
screen edge (i.e. the panel). To fix this, only enable this gesture if
the focus window is a fullscreen window.
