py-setuptools: updated to 40.6.1

v40.6.1
* Fixed regression where packages without author or author_email fields \ 
generated malformed package metadata.

v40.6.0
* Officially deprecated the requires parameter in setup().
* In pkg_resources.normalize_path, additional path normalization is now \ 
performed to ensure path values to a directory is always the same, preventing \ 
false positives when checking scripts have a consistent prefix to set up on \ 
Windows.
* Changed the warning class of all deprecation warnings; deprecation warning \ 
classes are no longer derived from DeprecationWarning and are thus visible by \ 
default.
* build_meta.build_sdist now includes setup.py in source distributions by default.
* Started monkey-patching get_metadata_version and read_pkg_file onto \ 
distutils.DistributionMetadata to retain the correct version on the PKG-INFO \ 
file in the (deprecated) upload command.
* Restricted the recursive-include setuptools/_vendor to contain only .py and \ 
.txt files.
* Changed Pyrex references to Cython in the documentation.
* Documented that the rpmbuild packages is required for the bdist_rpm command.
* Documented how to use setup.cfg for src/ layouts
* Added minimum version column in setup.cfg metadata table.
* Fixed a minor typo in the python 2/3 compatibility documentation.
* Updated installation instructions to point to pip install instead of ez_setup.py.
* Updated setuptools distribution documentation to remove some outdated information.
* Documented setup.cfg minimum version for version and project_urls.
* Added the concurrent.futures backport futures to the Python 2.7 test suite \ 
requirements.
