gnu: python-scikit-learn: Use OpenBLAS instead of ATLAS.

* gnu/packages/python.scm (python-scikit-learn)[inputs]: Replace "atlas" with
  "openblas".
* gnu/packages/python.scm (python-scikit-learn)[arguments]: Remove build phase
  'set-environment-variables, which is only needed when ATLAS is used.
