util/linuxfw: add container-friendly IPv6 NAT check (#11353)
Remove IPv6 NAT check when routing is being set up
using nftables.
This is unnecessary as support for nftables was
added after support for IPv6.
https://tldp.org/HOWTO/Linux+IPv6-HOWTO/ch18s04.html
https://wiki.nftables.org/wiki-nftables/index.php/Building_and_installing_nftables_from_sources
Additionally, run an extra check for IPv6 NAT support
when the routing is set up with iptables.
This is because the earlier checks rely on
being able to use modprobe and on /proc/net/ip6_tables_names
being populated on start - these conditions are usually not
true in container environments.
