    glib/tests/gdatetime.c: Fix TZ envvar test on Windows
    
    Windows does not recognize the "America/Recife" as a valid timezone
    identifier, so setting the TZ envvar to that will result in "UTC" to
    be returned on Windows.
    
    Instead, set TZ to be the Windows equivilant "SA Eastern Standard
    Time", and see whether that is indeed our identifier when we create the
    GTimeZone using that.
