Haddock derivations should define hydra-build-products

[andreabedini]

It would be simple create a nix-support/hydra-build-products in the derivation output to define the built haddock documentation as a product. This can be already achieved with

      {
        postHaddock = ''
          mkdir $doc/nix-support
          echo "doc haddock $docdir/html/index.html" >> $doc/nix-support/hydra-build-products
        '';
      }

but I think haskell.nix could do this by default at no cost.
