distutils: Replacing path to native path only to be done to non-native python packages

distutils: Replacing path to native python by path to python in the
image to support python packages with console-script setup resulted in
a "bad interpreter" error message because coreutils-native is not
a specified dependency of a number of native python packages.

We modify the change to apply specifically to non-native packages.
