haskell: don't error if isLibrary = true and no libraries exist
If empty directory isn't deleted, referer depenedencies will fail with: cp: missing destination file operand after '/tmp/nix-build-cabal-helper-0.8.0.2.drv-0/setup-package.conf.d/' This is currently only the case for cabal-install, as cabal2nix doesn't handle well buildable=False flags due to long-standing bugs in Cabal itself.
