zebra: fix routing socket AF_LINK handling on NETMASK
IPv6 netmasks use AF_LINK family type and puts the correct amount of
set bits in the data structure. If we only copy the SDL header we
won't get all IPv6 address length, we must copy the whole extension of
the `sockaddr_in6` struct (which is provided in `destlen` parameter).
