Include nftables and appropriate modules. Translate ip- and ebtables
rules to their nftables counterparts. Remove ip/ebtables and modules.
This change intentionally tries to keep structural changes at a minimum
to keep the rule translation comprehensible.
kmod-nft-bridge is not required for fff-node, because it was merged into

With this new package it is possible to do SNAT for client IPv4.
The user must set a router_ip in gateway.meta.router_ip, so an ip
address is available for peering interfaces and reachability.
Currently, no extra filtering is done, so the client interface should
only use ip ranges, which are already filtered from being announced
(e.g. 192.168.0.0/16).
Using NAT for IPv4 significantly reduces the need for big
Freifunk-global IP range allocations.
