SDL: only react to window focus changes if state actually changes

Browse source 
Because the state carries over for each call to
Impl_HandleWindowEvent, once the window has been focused,
events that do not change the focus state behave as if the
window was just refocused, anyway.

On linux i3wm, some such window events propogate
constantly in fullscreen mode.
