hackage2nix: Split configuration, auto disable hydra builds
We split configuration-hackage2nix.yaml into multiple files.  We bump
cabal2nix-unstable to get support for multiple config files in
hackage2nix.

* The file main.yaml is only supposed to be edited by humans.
* The file stackage.yaml is only supposed to be updated by the
  update-stackage.sh
* The file broken.yaml can be edited by humans, but probably future
  helpers will want to insert broken packages into this file based on
  hydra reports.
* The file transitive-broken.yaml is newly introduced to be generated
  by regenerate-transitive-broken-packages.sh

regenerate-transitive-broken-packages.sh makes a nix query (in
transitive-broken-packages.nix) which evaluates all haskellPackages
once with and once without "allowBroken" this way it get's a list of
packages which are broken by some transitive dependency, but does not
disable packages which have eval errors not caused by a broken package.
