test/e2e: fix podman run check dns flake 

For unknown reasons systemd-resolved sometimes responds with NXDOMAIN
instead REFUSED which it seems to use by default for a local name
without domain part. So the fact that this works at all right now is
super weird.

In any case we just want to make sure the name did not get resolved so
allow both here to fix the flake.
