Adjust the tests for the `pathlib.types` module so that they can be run against the `pathlib-abc` PyPI package, which is a backport of the module for older Python versions. Specifically, we add a `.support.is_pypi` switch that is false in the stdlib and true in the pathlib-abc package. This controls which package we import, and whether or not we run tests against `PurePath` and `Path`. For compatibility with older Python versions, we stop using `zipfile.ZipFile.mkdir()` and `zipfile.ZipInfo._for_archive()`.
