core/events: Don't update the cursor renderer on motion under X11

Browse source 
Doing so was unnecessary and seemed to cause feedback to Xorg resulting
in heavy stuttering and random freezes.

We do however keep the call to `meta_cursor_tracker_invalidate_position`
so as to not undo the intention of 9bdf4b35.

Suggested by Carlos Garnacho.
