[issue38691] importlib: PYTHONCASEOK should be ignored when using python3 -E

[Łukasz Langa]

Re-opening as it causes refleaks all across the stable buildbots. I can reproduce on macOS Catalina as well. Run this to see for yourself:

- ./python.exe -E -Wd -m test -uall,-gui -l -L -R: test_importlib

Reverting GH-18627 fixes the issue.
