This commit adds an error message if no repositories are defined in the dnfjson query. We had the issue in https://github.com/osbuild/bootc-image-builder/issues/922 that in a RHEL bootc-container no repositories are defined. Here the error is quite confusing, as it complains about error marking packages which is technically correct but hides the root of the problem. With this detect we can construct a more useful error message in the higher layers.
