tcp_xlate: Enclose LH flag values in parentheses

This fixes TCP flags matches:

| $ iptables-translate -A invalid -p tcp --tcp-flags SYN,FIN SYN,FIN -j DROP
| nft add rule ip filter invalid tcp flags & fin|syn == fin|syn counter drop

Although the generated rule is syntactically correct and accepted by
nft, it will be interpreted in a different way than expected since
binary AND takes precedence over OR.
