Set SO_REUSEADDR in regression test netcat.

Sometimes multiplex tests fail on Solaris with "netcat: local_listen:
Address already in use" which is likely due to previous invocations
leaving the port in TIME_WAIT.  Set SO_REUSEADDR (in addition to
SO_REUSEPORT which is alread set on platforms that support it).  ok djm@
