This patch fixes relayd not adding a host on an ARP request for the local
IP address.
When relayd is launched using the -L option, it was not adding the
necessary host routes when it receives an ARP request for the local
IP address.
This issue makes a host not able to connect to the device running
relayd until there is ARP traffic involving a third host.
