core: add dependent multicast route configured by kernel for IPv6
Pre-generate the device multicast route in the local table that are configured
by kernel when an ipv6-address is assigned to an interface.
This helps NM taking into account routes that are not to be deleted
when a connection is reapplied on an interface.
