      In previous versions of Nixpkgs,
      `<originalDerivation>.inputDerivation.requiredSystemFeatures` would
      always be the same as `<originalDerivation>.requiredSystemFeatures`. This
      meant that if a builder wasn’t able to build `<originalDerivation>` due
      to a lack of system features, then that builder would also not be able to
      build `<originalDerivation>.inputDerivation`.

      That was an aribtrary (and probably accidental) limitation. Building
      input derivations never requires any system features. This test checks to
      make sure that that limitation no longer exists.
