[issue11802] filecmp.cmp needs a documented way to clear cache

[Nadeem Vawda]

Because the lru_cache decorator doesn't provide any way to invalidate
stale cache entries.

Perhaps I should factor out the duplicated code into a separate class
that can then also be exposed to users of the stdlib. But that would only
apply to 3.3, so the uglier fix is still necessary for older versions.
