Add a failing test for a custom types module case

Any `types.*Type*` matches incorrectly as a `type(...)` comparison;
the regex `COMPARE_TYPE_REGEX` seems a bit too complicated
for what should be a simple comparison case.

Ref: https://github.com/PyCQA/pycodestyle/blob/main/pycodestyle.py#L147-L148

This reproduces the case in #830
