Peter Simons afca6145d4 haskell-generic-builder: simplify "package.conf.d" management
The builder creates a temporary package.conf.d database in $TMP that
contains everything required to build the current package (i.e. the
transitive closure of the package's propagated build inputs). These
files are no longer installed, however, we just install the package.conf
file for the package we're actually building. This means that
package.conf.d directory in $out won't have collisions anymore, which
simplifies the with-packages-wrapper.nix a bit.

Peter Simons 38e2e8702c ghcWithPackages: call this derivation exactly like the compiler it's based on
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.
