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 a single kernel module since Linux 4.17: [1]02c7b25e5f
