Extended Derivation type by a 'postInstall' field.

This is a hack, unfortunately, but it is a hack that we need to support 'ghc-mod', which needs some post-processing in order to work correctly. The proper solution to this mess is to implement Derivation as HList that can be extended in some object oriented fashion.
