  pinctrl: Don't send gARPs for localports

Ports of type 'localport' are present on every hypervisor and
ovn-controller is sending gARPs for them which makes upstream
switches to see its MAC address flapping.

In order to avoid this behavior, the current patch is skipping
localports when sending gARP/RARP packets.
