messageTray: Work around glitches with hover tracking

Browse Source 
St's hover tracking uses ClutterInputDevice, which unfortunately may use
an outdated cursor position to determine which actor is hovered. Using
MetaCursorTracker instead would fix this, but would require linking St with
libmutter - avoid this for now by manually fixing up Clutter's view of
the pointer position in the case where we rely on it working properly.
