toolhead: Reduce target buffer time to 1 second from 2 seconds

Browse Source 
During normal printing the host software would attempt to stay ahead
of the micro-controller by 2 full seconds.  Change that time to 1
second.  This should make the software more responsive to user
requests (such as pause requests).
