    Fix counting/ checking for leap years in mktime_utc()
    
    When HAVE_TIMEGM is undefined mktime_utc() might output one day shift (+86400s)
    for (years <= 1967 or years >= 2100) && month >= 3
    
    { .tm_mday = 1 .tm_mon = 2 .tm_year = 67 }
    mktime_utc() = -89436590    // Thu Mar  2 00:00:00 UTC 1967
        gmtime() = -89596800    // Wed Mar  1 00:00:00 UTC 1967
    
    { .tm_mday = 1 .tm_mon = 2 .tm_year = 200 }
    mktime_utc() = 4107628800   // Tue Mar  2 00:00:00 UTC 2100
        gmtime() = 4107542400   // Mon Mar  1 00:00:00 UTC 2100
