gnu: Use old setuptools in packages that relies on use_2to3 conversion.

This fixes a regression since 520cdf8058 where
the use_2to3 functionality was removed from setuptools.

* gnu/packages/graph.scm (python-louvain)[native-inputs]: Change from
PYTHON-SETUPTOOLS to PYTHON-SETUPTOOLS-57.
* gnu/packages/python-check.scm (python-parameterizedtestcase)[native-inputs]:
Likewise.
* gnu/packages/python-xyz.scm (python-anyjson)[native-inputs]: Add
PYTHON-SETUPTOOLS-57.
* gnu/packages/bioinformatics.scm (python-pyvcf)[native-inputs]: Change from
PYTHON-SETUPTOOLS-FOR-TENSORFLOW to PYTHON-SETUPTOOLS-57.
