Fixes #1857.
When we call cabal-plan-to-nix, we obtain the set of revised cabal files directly from the plan (which, in turn, are obtained from the index tarball). A stackage snapshot does not involve any planning and simply refers to specific hackage revisions (intentified by their hash and number). In this case we still need to obtain the revised cabal file from hackage before building packages.
Rather than putting this logic back in the builder (as it was before #1775), I suggest we put it into the layer that processes hackage.nix. The reason is that the builder should be agnostic about where a package comes from; in constrast, while processing hackage, we can be sure about where packages are from!
