st/nine: Avoid redundant SetCursorPos calls

Browse source 
For some applications SetCursorPosition
is called when a cursor event is received.

Our SetCursorPosition was always calling
wine SetCursorPos which would trigger
a cursor event.

The infinite loop is avoided by not calling
SetCursorPos when the position hasn't changed.
Found thanks to wine tests.

Fixes irresponsive GUI for some applications.
