hackage2nix: set "meta.hydraPlatforms = []" for builds that we know to be broken

http://hydra.cryp.to/jobset/nixpkgs/haskell-updates builds the entire package
set regularly. The subset of builds that have never succeeded is considered
"broken" and Hydra builds for those are generally disabled. Note that Users can
compile those packages just fine -- it's just that Hydra will not attempt to do
it.
