Revert the change to filter out deps of non-buildable components It does not work as intended and gives inconsistent results between cabal install and cabal configure. The problem with the approach was that we were filtering out the dependencies of non-buildable components at the end. But that does not help much since if one of the deps of the non-buildable component were not available then we would have failed earlier with a constraint failure. A proper solution would have to tackle it from the beginning, not just as a filter at the end. The meaning of build-depends and buildable: False needs more thought.
