vangyzen 192a6ce090 Fix ICMPv6 redirects
icmp6_redirect_input() validates that a redirect packet came from the
current gateway for the respective destination.  To do this, it compares
the source address, which has an embedded scope zone id, to the next-hop
address, which does not.  If the address is link-local, which should be
the case, the comparison fails and the redirect is ignored.

Insert the scope zone id into the next-hop address so the comparison
is accurate.

Unsurprisingly, this fixes 35 UNH IPv6 conformance test cases.
