arp(8): Add option -i to limit operations to one interface

This allows to limit the scope of operation to the ARP entries on a
particular interface, which should be useful on machines with lots of
network interfaces, e.g., inter-VLAN routers.

This new option will also be used in /etc/pccard_ether.

Taken from FreeBSD (r117729, r154162) with modifications.
