ghcWithPackages: call this derivation exactly like the compiler it's based on

Browse Source 
Furthermore, export "name" and "version" attributes that match those of the
underlying compiler. These changes make a ghcWithPackages-generated wrapper
look exactly like a normal GHC derivation and it can be used anywhere in
Nixpkgs where a normal GHC would be used.
