ecore_drm: send a fake motion event to let other know the initial pos of mouse

Summary:
At the first time after finishing booting, the position of mouse cursor is in the
center of screen. But e doesn't know it. ecore_drm should let e know the initial
position of cursor by sending a fake motino event.
