sdist is missing test requirements file

[mtelka]

Describe the bug

The sdist package at PyPI is missing requirements/test.txt and/or requirements/test.in file. Without them it is hard to know what Python projects are needed to successfully run test.

This causes some inconvenience during packaging of aiohttp for OpenIndiana since we are running tests to make sure our packages works properly.

To Reproduce

Download sdist from PyPI and unpack it.

Expected behavior

There is requirements/test.txt and/or requirements/test.in file.

Fair. Integrating https://github.com/re-actors/checkout-python-sdist would be a welcome contribution if someone would want to make a PR.
