Add non-invasive option to disable python3-apport site customization?

I was helping a colleague debug something, and found that `python3-apport` was intercepting a `dlopen` error, and turning it into a segfault.

I then disabled the customization as I indicated here: https://askubuntu.com/a/1305370/692420
(TL;DR I removed `/etc/python3.6/sitecustomize.py`)

Ideally, could there be a better way to disable the Python hook, even if just locally?

Ideas / Suggestions:

- The Python code perhaps does a *quick* file of apport settings to see if apport is enabled? (may be too slow)
- The Python code briefly checks for the existence of some file, e.g. `/etc/python3.6/disable-apport`
- The Python code briefly checks for an environment variable?
- Stick with just manually disabling `sitecustomize.py`, and add that to documentation somewhere?

Thanks!
