haskell: fix build of all tensorflow packages

* Since this commit changes configuration-hackage2nix.yaml it
  requires a hackage-packages.nix upgrade.

* Moved the tensorflow overrides out of configuration-ghc-8.2.x.nix
  and into the dedicated file configuration-tensorflow-ghc-8.2.x.nix
  for better readability.

* Add overrides for all the packages in the tensorflow-haskell
  repository.
