client inputs: stop blinking keyboard when out of focus

We could introduce another boolean to prevent changes, or just reuse
_active_modifiers_event = true to prevent further update.

Additionaly this patch restore the keyboard state when focusing out,
which is fine when dealing with full remote desktop, but should be
reconsidered if/when SPICE supports remote windows managed by client
window manager for instance, imho.
