Needs a rebase, but I tested nix-build pkgs/test/release when merging this into current master, still works, so this LGTM!

[philiptaron]

Thanks, rebased.

removing test-pkgs seems like it creates a cycle in freshBootstrapTools.test-pkgs as shown by:

nix-instantiate  --eval --strict -E '(import ./pkgs/top-level/release-attrpaths-superset.nix { }).paths'  

restored in #354004

PR immediately accepted and merged. I bet you're on Darwin. All my testing (and the CI checks) are on x86_64-linux, and I've noticed that these tests are incredibly sensitive to which system they're evaluated for.
