haskell.compiler.integer-simple: construct using include list

There won't be any new integer-simple compilers and they are already in
the minority, so converting the mechanism to an include list is much
better. Maybe native-bignum should now become an exclude list
additionally?

Verified that nix-env -qaP -A haskell.compiler output stays identical.
