This fixes https://github.com/ValveSoftware/Proton/issues/911

If the game is ran with numlock enabled, Wine will try to sync on the
first key event. The game uses dinput in exclusive mode, so our low
level keyboard hook prevents simulated numlock press in
update_lock_state. Thus, we simulate the same key press again on
following key events. It means that all key events will result in two
events on Wine side: (simulated) numlock press and the actual key press.
The patch avoids that by forcing Wine-side state to be the same as X
server state.

For this particular case, the game could theoretically be fixed on
dinput side (as part of rewrite on top of HID?), but it's still a bug in
winex11.drv that any other hooks could expose.
