Peter Simons 5d5b51dfc0 haskell-generic-builder: add a passthru attribute 'isHaskellLibrary' to every derivation
The presence of this attribute allows us to recognize Haskell derivations.
Furthermore, we can use it to distinguish libraries from executables (which is
useful for the code that's generating the wrapper).
