Subject: [PATCH net] selftests: net: add missing config for nftables-backed iptables

From: Jakub Kicinski <[email-masked]>

Modern OSes use iptables implementation with nf_tables as a backend,
e.g.:

$ iptables -V
iptables v1.8.8 (nf_tables)

Pablo points out that we need CONFIG_NFT_COMPAT to make that work,
otherwise we see a lot of:

  Warning: Extension DNAT revision 0 not supported, missing kernel module?

with DNAT being just an example here, other modules we need
include udp, TTL, length etc.
