firewall: Allow traffic from multicast networks

Browse Source 
The multicast network segment 224.0.0.0/4 is used for a lot of
different services provided by the local ISP's. (IPTV etc.)

We have to allow traffic from this networks when using one of
the BOGON blocklists in order to get those ISP services still
accessable.
