systemd: Enable DHCPv6 and Ipv6AcceptRA.

This will enable a COS node to get an ipv6 address via DHCP, and apply
routes advertised by the DHCP server.

In addition, it is also adding a patch where the boot process of  VM
with the above configuration enabled should not regress if there is only
IPV4 address available.
