Add support for ttl translation

This patchset adds ttl translation to nftables by adding ip ttl to the buffer everytime a ttl match is hit as it is necessary to mention the protocol version with ttl, that is,

$ sudo nft .. ttl 3 ..             won't work but
$ sudo nft .. ip ttl 3 ..          would work.
Also, since adding ip to the buffer in the code for ttl won't look
suitable, some amendments have been done in the nft-ipv4 code.

iptables: nft-ipv4: Add ip ttl to the buffer
extensions: libipt_ttl: Add translation to nft
