Add translation for module cpu to nftables.
Examples:
$ sudo iptables-translate -A INPUT -p tcp --dport 80 -m cpu --cpu 0 -j ACCEPT
nft add rule ip filter INPUT tcp dport 80 cpu 0 counter accept
$ sudo iptables-translate -A INPUT -p tcp --dport 80 -m cpu ! --cpu 1 -j ACCEPT
nft add rule ip filter INPUT tcp dport 80 cpu != 1 counter accept
