    Handle registries with incorrect certs correctly

    We actually end up allowing registries with incorrect certificates in
    the upload code so they get treated the same as inscure registries.
    This change updates the return code of the is_insecure_registry to match
    how we handle these registries in the image uploader. Additionally, this
    means that when the container image prepare code runs, we will correctly
    include these registries that have ssl enabled but incorrect
    certificates will correctly be included in the
    DockerInsecureRegistryAddress setting.
