PyPI tarball missing required files

Describe the bug

The tarball uploaded to PyPI does not contain requirements/* files which are required to run the setup.py file.

Reproduction steps

$ wget https://files.pythonhosted.org/packages/source/k/kornia/kornia-0.6.0.tar.gz
$ tar zxf kornia-0.6.0.tar.gz
$ cd kornia-0.6.0
$ python setup.py install
...
Traceback (most recent call last):
  File "setup.py", line 43, in <module>
    "x": load_requirements("requirements/x.txt"),
  File "setup.py", line 38, in load_requirements
    with open(filename) as f:
FileNotFoundError: [Errno 2] No such file or directory: 'requirements/x.txt'

Expected behavior

I would expect the setup.py to function correctly. I believe there’s a setuptools option to control which files get included in the upload tarball.

Environment

- PyTorch Version (e.g., 1.0): 1.10
- OS (e.g., Linux): macOS
- How you installed PyTorch (`conda`, `pip`, source): `spack`
- Build command you used (if compiling from source): `python setup.py install`
- Python version: 3.8.11
- CUDA/cuDNN version: N/A
- GPU models and configuration: N/A
- Any other relevant information: N/A

Additional context

ok - seems that package_data is what we want here

Seems that it works with data_files=[('', ['requirements/x.txt'])], – but not e.g with data_files=[('', ['requirements/*.txt'])],

Still with the issue of getting the test files in.
