Infra: expose and use checks for vmOptions and nixosConfigurations (#488)

Browse source 
Following Fediversity/Fediversity#478 (comment), here is a PR that plugs the infra's `vmOptions` and `nixosConfigurations` outputs into flake checks, instead of calling random Nix commands from the CI. There is still a bit of magic in the CI, but that's because we don't have yet a Nix-aware CI that exposes one job per flake check.

Machines that are _not_ Fediversity VM could be physical machines, or
VMs that live outside Fediversity, eg. on Procolix's Proxmox.
