[PATCH iptables] add missing icmpv6 codes (rfc4443) in REJECT

[PATCH iptables] add missing icmpv6 codes (rfc4443) in REJECT

[Andreas Herz]

RFC 4443 added two new codes values for ICMPv6 type 1:

 5 - Source address failed ingress/egress policy
 6 - Reject route to destination

And RFC 7084 states in L-14 that IPv6 Router MUST send ICMPv6 Destination
Unreachable with code 5 for packets forwarded to it that use an address 
from a prefix that has been invalidated.
