kerneltest: use my branch on stg to investigate errors

See https://pagure.io/fedora-infrastructure/issue/11952 , I'm
trying to get kerneltest / kernel-tests to work with OIDC auth
but getting "invalid input file" errors; need to deploy a
branch with the real errors behind that message logged at a
level we can see.
