fuzz: run the main-loop in fork-server process
Without this, the time since the last main-loop keeps increasing, as the fuzzer runs. The forked children need to handle all the "past-due" timers, slowing them down, over time. With this change, the parent/fork-server process runs the main-loop, while waiting on the child, ensuring that the timer events do not pile up, over time.
