When pungi injects its repo it does it into the file that it has been
pointed at (i.e. the toplevel json file). We need to move it from the
fedora-workstation-base.json into fedora-atomic-workstation.json
otherwise pungi will end up trying to pull from the 'fedora-rawhide'
repo too and it will fail.
This is obviously confusing but right now "ostree workstation" is really
"Atomic". I'm not changing the refs or the names of the manifest JSON files yet,
but the high level idea here is we have:
- workstatoin-base (should be like comps...that's another issue)
- atomic (inherits desktop-base, adds rpm-ostree + container tooling)
Also I added a compat symlink so pungi doesn't need an immediate change.
