This reverts commit 4f91e9599f.
This broke:
when I applied this pr, `--print-out-paths` wouldn't print anything:
```
shell-for-nix-env % nix build --print-out-paths .#legacyPackages.aarch64-darwin.homeConfigurations.macos.activationPackage
```
After dropping the patches from my fork, it does again.
```
shell-for-nix-env % nix build --print-out-paths .#legacyPackages.aarch64-darwin.homeConfigurations.macos.activationPackage
/nix/store/s8mlcalszdml0v8172w4hwqnx0m6477r-home-manager-generation
```
