suspend: make ps/2 devices wakeup the guest

This patch adds wakeup support to ps/2 emulation.  Any key press on the
ps/2 keyboard will wakeup the guest.  Likewise any mouse button press
will wakeup the guest.  Mouse moves are ignored, so the guest will not
wakeup in case your mouse crosses the vnc window of a suspended guest by
accident.
