Bug#923937: debian local patch uses the deprecated imp module, causing the python-scipy autopkg tests to fail

The debian local patch uses the deprecated imp module, causing the python-scipy
autopkg tests to fail.

While joblib is patched out, there is still sklearn/utils/_joblib.py which tries
to import the local module when SKLEARN_SITE_JOBLIB is not defined. I think this
should be patched as well to always import the site joblib.
