* download-using-manifests: don't check the cryptographic hash of
  downloaded files; rather, check the hash of the unpacked store
  path.

  When the server produces bzipped NAR archives on demand (like Hydra
  does), the hash of the file is not known in advance; it's streamed
  from the server.  Thus the manifest doesn't contain a hash for the
  bzipped NAR archive.  However, the server does know the hash of the
  *uncompressed* NAR archive (the "NarHash" field), since it's stored
  in the Nix database (nix-store -q --hash /nix/store/bla).  So we use
  that instead for checking the integrity of the download.
