passt: Introduce a DHCPv6 server

This implementation, similarly to the IPv4 DHCP one, hands out a
single address, which is the same as the upstream address for the
host.

This avoids the need for address translation as long as the client
runs a DHCPv6 client. The NDP "Managed" flag is now set in Router
Advertisements.
