nclient6: listen on link-local addr
This allows for multi-NIC DHCPv6 in parallel.
Otherwise:
2020/02/20 05:01:34 Could not configure eth1 for IPv6: listen udp6 %eth1:546: bind: address already in use
2020/02/20 05:01:34 Could not configure eth4 for IPv6: listen udp6 %eth4:546: bind: address already in use
2020/02/20 05:01:34 Attempting to get DHCPv6 lease on eth2
2020/02/20 05:01:34 Could not configure eth0 for IPv6: listen udp6 %eth0:546: bind: address already in use
2020/02/20 05:01:34 Could not configure eth3 for IPv6: listen udp6 %eth3:546: bind: address already in use
