[Android]Use zh instead of zh-rTW as output folder of zh_TW translation

Android does not support zh-HK, yet many vendors still ship devices with
this locale. By default Android will fall back to English when it sees
zh-HK. This CL changes the output folder of our traditional Chinese
folder from zh-rTW to zh so that zh_HK users will fall back to
traditional Chinese.

This CL does not affect simplified Chinese. It will affect other
unsupported Chinese locales such as zh_sg (if any).
