win32: fix semantics of POSIX 2008 locale stubs

This sliences some warnings about unused values and statements with no
effect, but it also fixes a logic error with freelocale(), since
previously it would not work as expected when used in the body of an if
statement without braces.

Uses real functions, because with macros, I don't think there is a way
to silence the "statement with no effect" warnings in the case where the
return value of uselocale() is ignored.

As for replacing the these functions with working implementations, I
don't think this is possible for mpv's use-case, since MSVCRT does not
support UTF-8 locales, or any locale with multibyte characters that are
three or more bytes long. See:
