[bug#33515] [PATCH 0/5] Cuirass/Hydra: evaluate jobs in an inferior

I’ve pushed the patches to the ‘wip-ci-inferior’ branch and created
these two jobsets:

  https://berlin.guixsd.org/jobset/wip-ci-inferior
  https://hydra.gnu.org/jobset/gnu/wip-ci-inferior

Evaluation with Cuirass on berlin went fine.

I suspect evaluation on hydra will fail though, because it’s probably
running an older Guix version; we’ll have to upgrade there.  Mark, would
you like to take a look?
