winex11.drv: Allow keyboard layout score to be negative.

The keyboard layout matching algorithm can assign a negative score
to a keyboard layout. If the user has a strange keyboard layout,
possibly a custom one, it might happen that all keyboard layouts
known by Wine get a negative score. This is not an error in itself,
and we should still strive to find the best match.
