KevinLiang10 b040094b90 util/linuxfw: reorganize nftables rules to allow it to work with ufw
This commit tries to mimic the way iptables-nft work with the filewall rules. We
follow the convention of using tables like filter, nat and the conventional
chains, to make our nftables implementation work with ufw.

Updates: #391

KevinLiang10 a3c7b21cd1 util/linuxfw: add nftables support
This commit adds nftable rule injection for tailscaled. If tailscaled is
started with envknob TS_DEBUG_USE_NETLINK_NFTABLES = true, the router
will use nftables to manage firewall rules.
