[Forward compatibility][BUG] `pkg_resources.extern.VendorImporter` lacks `exec_module()` method

See original GitHub issue

This causes an ImportWarning that effectively explodes in envs with a strict warning handling (filterwarnings = error) — like pytest — under Python 3.10-dev that ships setuptools v47.1.0. But I checked that the importer is still missing that method. The simple repro is:

$ python3.10 -W error -c 'import pkg_resources' 
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "~/.pyenv/versions/3.10-dev/lib/python3.10/site-packages/pkg_resources/__init__.py", line 57, in <module>
    from pkg_resources.extern import six
  File "<frozen importlib._bootstrap>", line 1026, in _find_and_load
  File "<frozen importlib._bootstrap>", line 1005, in _find_and_load_unlocked
  File "<frozen importlib._bootstrap>", line 681, in _load_unlocked
ImportWarning: VendorImporter.exec_module() not found; falling back to load_module()
