hydra-eval-jobs: Transmit original Nix error when handling aggregate jobs

It might happen that a job from the aggregate returned an error!

This is what the vague "[json.exception.type_error.302] type must be string, but is null"
was all about in this instance; there was no `drvPath` to stringify!

So we now actively watch for errors and copy them to the aggregate job.
