haskellPackages.mkDerivation: don't ev allPkgconfigDepends too early

Browse source 
Just getting the length of allPkgconfigDepends now may require a quite
expensive and involved function to be execute, so it should be put off
as long as possible. We can achieve this by moving the assert for
pkg-config being available next to its inclusion in nativeBuildInputs.

This solves the infinite recursion triggered by hercules-ci-cnix-store.
