[Petr Vorel]

Hi Alexey,

> New tests: ip6tables, nft6.
great idea, just there is a regression in nft01.sh, see below.

change to tst_require_cmds() does not catch missing nft:

nft check broke, original:
nft01 1 TCONF: 'nft' not found

now:
/bin/sh: 1: nft: not found
nft01 1 TBROK: nft add table ip filter failed

one of these fixes it (take whatever you like. Both variants check nft twice,
I'd ignore it).
