Updated to solution to use the functools.lru_cache().
Restores the API so that purge() is not needed
(because the cache never gets big).

Partially closes issue 9356. Thanks to Brian Brazil for the patch.

This introduces a 'purge' function for the fnmatch module analogous
to the 'purge' function in the re module.
