Remove debugging printf(.) that was left in unixcomm.c

When Medley closes a stream open to a process it uses a "unixcomm"
command (3) which should close() the communication channel open with
the process and give it a chance to handle that and exit cleanly
before using a SIGKILL on it.  We can't determine apriori whether the
process is going to cooperate, so we're stuck trying for up to 0.1s
(arbitrary choice!)  waiting for the process to exit, then it gets a
SIGKILL, and we wait up to 0.1s again to see that it really exited.
