Eelco Dolstra eebb241519 * Write the list of mirrors to a file that we can reuse between
fetchurl instantiations, instead of passing the mirrors to fetchurl
  instantiations via environment variables.  This makes the resulting
  store derivations (.drv files) much smaller, which in turn makes
  nix-env/nix-instantiate faster (4.8 -> 4.2 seconds on nix-env -qa
  --out-path).
