nhrpd: Add support for forwarding multicast packets
Forwarding multicast is a pre-requisite for allowing multicast based routing
protocols such as OSPF to work with DMVPN
This code relies on externally adding iptables rule. For example:
iptables -A OUTPUT -d 224.0.0.0/24 -o gre1 -j NFLOG --nflog-group 224
