libnftables: Implement JSON output support
Although technically there already is support for JSON output via 'nft export json' command, it is hardly useable since it exports all the gory details of nftables VM. Also, libnftables has no control over what is exported since the content comes directly from libnftnl. Instead, implement JSON format support for regular 'nft list' commands.
