Depends on https://github.com/nix-community/nix-eval-jobs/pull/349 & #1421. Almost equivalent to #1425, but with a small change: when having e.g. an aggregate job with a glob that matches nothing, the jobset evaluation is failed now. This was the intended behavior before (hydra-eval-jobset fails hard if an aggregate is broken), the code-path was never reached however since the aggregate was never marked as broken in this case before.
