Log Message:
Enable to remove multiple ARP/NDP entries for one destination

The kernel can have multiple ARP/NDP entries which have an indentical
destination on different interfaces. This is normal and can be
reproduce easily by ping -I or ping6 -S. We should be able to remove
such entries.

arp -d <ip> and ndp -d <ip> are changed to fetch all ARP/NDP entries
and remove matched entries. So we can remove multiple entries
described above. This fetch all and selective removal behavior is
the same as arp <ip> and ndp <ip>; they also do fetch all entries
and show only matched entries.
