I've had intermittent problems with the pasta DNS tests in podman. Here are some fixes that address at least some of them.

I guess we'll have to include dig in the images: dig has two advantages

dig has infinite advantages. I love dig. I deliberately choose not to include it in quay.io/testimage because of its dependencies: bind-tools requires a lot of useless-to-us stuff, and bloats testimage from 12MB to 19.

@Luap99 @edsantiago where do we stand here on this one? seems like something we'd want to merge?

[Luap99]

Unless we get version that passes tests there doesn't seem to be anything for us to do so this is waiting on @dgibson.

@Luap99 @edsantiago, finally got around to revising this, sorry it took so long.

A bunch of the Fedora 41 and rawhide tests are failing. I think it looks like an infrastructure issue unrelated to the actual changes.

New version pushed. Only change is a rebase + an extra patch attempting to address @edsantiago's comment.
