commit 10cc7ecacd631368e23691a77dbfe63ac6ca855f
Author: Robert Frohl <rfrohl@suse.com>

Dontaudit dac_override for iptables_t
There are AVCs observed during rootless docker 'systemctl --user restart
docker.service', but no functional impact.
Minimal steps to reproduce:
> sudo modprobe ip_tables
> # creates /proc/net/ip_tables_names
> systemctl --user restart docker.service
> # reproduces the AVCs
