[issue14067] Avoid more stat() calls in importlib

[Antoine Pitrou]

New submission from Antoine Pitrou <pitrou at free.fr>:

This is an experimental patch that limits the frequency of stat() calls in _FileFinder.find_module(). It speeds up finding modules by 2x here, but unfortunately breaks some tests (which expect modules to appear immediately when created).
