Netcat is able to handle multiple connections when "-k, --keep-open"
"-e command, --exec command" by forking the netcat. Prevent this
behavior by allowing only one connection at a time. This also
prevents the test getting stuck on cleanup as the netcat PID
wouldn't be added to the cleanup script.
Fixes: d15b12da6fe6 ("northd: Add ACL Sampling.")
