daemon: plug memory leakrs/daemon-plug-child-leak

Call child_process_clear() when a child ends to release the memory
allocated for its environment.  This is necessary because unlike all
other users of start_command() we don't call finish_command(), which
would have taken care of that for us.

This leak was introduced by f063d38b (daemon: use cld->env_array
when re-spawning).
