There's no need to add one second to the event time in callout_cc_add()
if this one is scheduled in the past. This was a braino derived from my
previous experiments. Moreover, there's no need to call binuptime(), but,
in turn, event times in the past may be silently converted to
cc_softticks, avoiding the bintime() overhead.

As an added bonus, we can avoid to start our scan of the wheel 1/HZ
backward in the past, gaining in terms of performances.
