Add translation for target MARK to nftables.
Examples:
$ sudo iptables-translate -t mangle -A PREROUTING -j MARK --set-mark 12
nft add rule ip mangle PREROUTING counter mark set 0xc
$ sudo iptables-translate -t mangle -A PREROUTING -p tcp --dport 22 -j MARK --set-mark 2
nft add rule ip mangle PREROUTING tcp dport 22 counter mark set 0x2
