config: pipeline: Fix failures caused by unsuccessful checkouts

- Some branches have disappeared. Remove those branches.
- Some branches have been renamed.

There was for-kernelci branch present in peterz's tree which has
disappeared. I'm replacing some other branch for now until we get a
reply from him.

Close: #888
