Since commit 0624107 we use the aardvark per container dns functionality. This means we should only have the aardvark ip in resolv.conf otherwise the client resolver could skip aardvark, thus ignoring the special dns option for this container.

Fixes #17499

Does this PR introduce a user-facing change?

podman run --dns ... --network ... will no longer add host nameservers to resolv.conf when aardvark-dns is used.

LGTM. The surrounding tests could use some cleanup, but not worth a repush

tests failing. network disconnect looks like it needs a netavark special-case; the ithers, no idea.
