Leave environment.variables untouched and wrap the utilities that are
added to environment.systemPackages. This avoids problems where shells
fail to source environment.variables.

Motivation for this change

I had a very frustrating situation where the fish shell failed to source HYDRA_DBI set by environment.systemPackages and the hydra-create-user utility fell back to a stale Sqlite codepath.

Things done
  • Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS linux)
  • Built on platform(s)
    • NixOS
    • macOS
    • other Linux distributions
  • Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
  • Tested compilation of all pkgs that depend on this change using nix-shell -p nixpkgs-review --run "nixpkgs-review wip"
  • Tested execution of all binary files (usually in ./result/bin/)
  • Determined the impact on package closure size (by running nix path-info -S before and after)
  • Ensured that relevant documentation is up to date
  • Fits CONTRIBUTING.md.

This patch removes HYDRA_DBI, HYDRA_CONFIG, and HYDRA_DATA from the global environmental variables, which I can't be sure wont cause problems for all deployments.

@ehmry thanks for your PR! Unfortunately I had to close it since this is a duplicate of #82507 which is also a bit nicer since it uses buildEnv rather than fixing duplications with meta.priority.

I'm very sorry I forgot about this PR and you fixed the issue yourself!
