Subject: [PATCH] locale: getlocale may return None's (#7562)

According to the docs at https://docs.python.org/3/library/locale.html#locale.getlocale, this function may return None for either of the two items in the return sequence, which is missed in the current form.

Also adjust `locale.setlocale()`, which can accept a tuple of `(None, None)` for the second argument.
