postgresql: remove references to llvm-dev on darwin as well

The !isDarwin condition seems to have been put in place only because of the
use of patchelf, which in turn seemed to be necessary because of nuke-refs.

Replacing the big nuke with the more granular remove-references-to allows
enabling this for darwin, too.
