winex11: Update the state of all keys on KeymapNotify. 

The Binding of Isaac transitions in and out of fullscreen when the "F" key is
pressed. Specifically, it will swap states when receiving WM_KEYDOWN,
provided that the previous key state was not pressed (i.e. bit 30 is 0).
However, as part of the process of transitioning, it hides and shows its
window, causing it to temporarily lose focus. If the F key is released while
the window does not have focus, Wine misses this fact, and thinks that the
key was already pressed the next time it is pressed, causing the game to
refuse to change focus. Windows will not deliver WM_KEYUP messages to a
window that does not have focus, but it will always report the true previous
state of any key on the keyboard when requested.
