@lang/ghc94: Fix broken "make bootstrap"

Bootstrapping the compiler without "cabal-install" is something GHC devs
rarely do, and it keeps bitrotting. This time I could make it work again,
but at some point we might end up having to distribute binaries of
cabal-install for each platform.

# This script extracts the package DB originally came from GHC you are
# using. Only needed when you create a hadrian bootstrap archive.
