Use host's resolv.conf if no network namespace enabled
My host system runs Fedora Silverblue 29 and I have NetworkManager's
`dns=dnsmasq` setting enabled, so my `/etc/resolv.conf` only has
`127.0.0.1`.
I also run my development podman containers with `--net=host`
for various reasons.
If we have a host network namespace, there's no reason not to just
use the host's nameserver configuration either.
This fixes e.g. accessing content on a VPN, and is also faster
since the container is using cached DNS.
I know this doesn't solve the bigger picture issue of localhost-DNS
conflicting with bridged networking, but that's far more involved,
probably requiring a DNS proxy in the container. This patch
makes my workflow a lot nicer and was easy to write.
