doc/nft.xml: mention nftables earlier

Mention nftables earlier in the documentation, so users have more context on what
we are talking about.

This is Debian bug #887718, which contains:

<<<
Currently one must read down 100 lines before it is even mentioned.
You might want to make the connection between "nft" and "nftables" as
early as the NAME or DESCRIPTION.
