From: Cathy Hu
pasta accesses /etc/resolv.conf, which needs search permissions
in openSUSE since the folder structure for the older
sysconfig-netconfig is different than in fedora (which uses
systemd-resolved)
this replaces the manual allow rules with the sysnet_read_config
interface in passt and pasta
