fetchTarball: Use "source" as the default name
This ensures that it produces the same output as fetchgit:

  $ nix eval --raw '(builtins.fetchgit https://github.com/NixOS/patchelf.git)'
  /nix/store/ghigrkw02l440g8vfxa9wj4c3zpfmw99-source

  $ nix eval --raw '(fetchTarball https://github.com/NixOS/patchelf/archive/master.tar.gz)'
  /nix/store/ghigrkw02l440g8vfxa9wj4c3zpfmw99-source
