0.19 tries ip6tables even if ipv6 is disabled for the node

Hi,

0.19 tries ip6tables even when ipv6 is disabled for the node;

[netclient] 2023-05-10 15:10:57 Starting firewall...
[netclient] 2023-05-10 15:10:57 iptables is supported
[netclient] 2023-05-10 15:10:58 failed to intialize firewall: couldn't get ipv6 filter table chains, error: running [/sbin/ip6tables -t filter -S --wait]: exit status 3: modprobe: can't change directory to '/lib/modules': No such file or directory
ip6tables v1.8.8 (legacy): can't initialize ip6tables table `filter': Table does not exist (do you need to insmod?)
Perhaps ip6tables or your kernel needs to be upgraded.

Not 100% sure, but I get the impression ipv4 iptables rules are therefore not set either.

Had to;

modprobe ip6table_raw ip6table_mangle ip6table_nat ip6table_filter nf_nat

on the host to get rid of the error.
