gtk: Remove coordinates double-translation

Remove our own translation in the mouse event capture code, as that
translation will be done through the navigation interface.

Tested by resizing the window created by:
gst-launch-1.0 -v videotestsrc ! navigationtest ! glupload ! glcolorconvert ! tee name=t  ! gtkglsink
and checking that the cursor follows the mouse as expected.
