    Bug 767824 - Some UTC timezones incorrectly recognized on Windows 7
    
    The condition removed erroneously excluded UTC-based and DST-less
    timezones and so left the GArray with no contents, so GTimeZone functions
    returned whatever random garbage was in memory.
    
    (cherry picked from commit 35b401c8bb0c7bb9324e7d8ae0e5d0a63f98872c)
