Andreas Haas c5c546fb7f X11: Don't reset mouse cursor theme. 
On KDE (and possibly others) the "default" cursor theme is actually some system default, not the one you've set in the desktop setting.
This was especially annoying when using a white cursor, as Godot would then reset back to a dark one.
In my case it was also keeping the cursor from changing its shape.
