Johan Malm ce8420d978 key-state: make nr-pressed-keys check more accurate
...to avoid counting keys which never send release events and thus
disable all keybinds.

We do not want to match keybinds if additional 'normal' (non-modifiers)
are pressed at the samet time. We must ignore keys which do not send
release events such as XKB_KEY_ISO_Next_Group and XKB_KEY_XF86WakeUP.
