Subject: Use GdkKeymap to listen for keyboard modifier changes

Connect to the GdkKeymap::state-changed signal to detect when the client
keyboard modifiers have changed. This keeps the client and the guest in sync
even when the SpiceDisplay widget isn't focused. New values are only sent down
to the guest if the new value is different than the current value.
