kernel32: Mac: If language is less specific variant of locale, keep locale.

For a Mac user in Australia, for example, the out-of-the-box configuration is
that the preferred language is generic English ("en").  Their formats locale
should be Australia ("en_AU").  Detect that case and don't override
LC_MESSAGES.
