extensions: libxt_connlabel: Add translation to nft
Add translation for connlabel to nftables.
For examples:
# iptables-translate -A INPUT -m connlabel --label bit40
nft add rule ip filter INPUT ct label bit40 counter
# iptables-translate -A INPUT -m connlabel ! --label bit40 --set
nft add rule ip filter INPUT ct label set bit40 ct label and bit40 != bit40 counter
