hydra-eval-jobs: Fix building against the latest unstable Nix

Dependencies

• [2] PMNWRTGJ Add multiple output support
• [3] DPYJFBXU hydra-eval-jobs: Support meta.license being a list
• [4] 5MNUNZWR * Store meta.maintainers.
• [5] KD5237CU * eval-jobs now efficiently evaluates all Hydra jobs from a
• [6] POPU2ATH * hydra_scheduler: use eval-jobs.
• [7] YGRLM2SK * Export all relevant info about the derivation.
• [8] 3PNG7NIB Remove trailing whitespace
• [9] ZTQEU5QS Hydra: Add support for maxSilent meta attribute (also already added timeout, but not implemented the actual timeout for the build yet)
• [10] AEKIREIH * Updated hydra_eval_jobs for the new evaluator.
• [11] 7YCFGMZB * Report evaluation errors per job, and don't bail out if a job fails
• [12] 4LWGZL33
• [13] HVXL2XUZ
• [14] FMJMW4PU
• [15] A63IHCMX * Register GC roots properly.
• [16] JTHWA6AM Rename aggregate members to constituents
• [*] 4N5APGRG * Start of a helper tool to evaluate job expressions efficiently.
