File winewayland-no-enter-move-if-relative.patch of Package wine

Stop sending a mouse move on surface enter if the last move was relative.
This reduces sudden movement jumps if a surface is in relative pointer mode and loses then regains focus.
Preventing them entirely would require some more rework..
