tox jobs: pin to correct nodesets; use host networking for containerfile
These must have broken when we switched the base nodes to Jammy.
Update to use compatible versions of distros.

We need to squish another gate-breaking change in here to update the
containerfile "podman build" calls to use "--network host".  We added
this with Ia885237406bf4c7b9d49b349f374558ae746401f and the only
external user I can find is kayobe, which is setting this anyway.

I honestly haven't 100% root-caused what changed to require this; the
last time our containerfile jobs ran and worked has unfortunately been
purged so I can't compare versions to try and pinpoint something;
i.e. this may be a podman bug or feature.  At first I thought it
related to the networking plugin package from the Depends-On (which is
still useful for the right packages) but that didn't help get the
bridge networking working.

=============
containerfile
=============

Base element for creating images from container files (aka
Dockerfiles).

Usually this element will be called via a more specific distro element
which provides an environment for building a full image.  This element
will search active elements for a container file located in
``containerfiles/${DIB_RELEASE}``.

Alternatively, to use this element directly supply the path to a
container file in the environment variable
``DIB_CONTAINERFILE_DOCKERFILE``.

Set ``DIB_CONTAINERFILE_RUNTIME`` to ``docker`` to use Docker for building
images (default is ``podman``).

Set ``DIB_CONTAINERFILE_RUNTIME_ROOT`` to ``1`` to run the runtime
(Docker or ``podman``, per above) as ``root``.

Set ``DIB_CONTAINERFILE_NETWORK_DRIVER`` to a network driver of your choice
(e.g. host) to use it instead of the default bridge during build.
