scripts/make-release: fix PyPI upload by using twine

Upload via 'python2 setup.py sdist upload' is deprecated.
Worse, it did not work from the default branch due to a unicode character in the README.rst file,
even though it was the same case on stable.

Following output is given:

    WARNING: Uploading via this command is deprecated, use twine to upload
    instead (https://pypi.org/p/twine/)

Fix both points by using 'twine' to do the upload.
