QLocale: use qsnprintf instead of deprecated sprintf

Fixes warnings such as

 qtbase/src/corelib/text/qlocale_tools.cpp:321:5: warning: 'sprintf' is deprecated: This function is provided for compatibility reasons only. Due to security concerns inherent in the design of sprintf(3), it is highly recommended that you use snprintf(3) instead. [-Wdeprecated-declarations]

from AppleClang.
