Subject: [PATCH] Remove checkChineseLocale

This was introduced by commit 396d31a0a75beae6d3bd46dba22e7ce39292d9b2. I just did some further testing and:

* zh_rCN and zh_rTW are the only zh locales you can pick before Android 7;
* Since Android 7, user can use locale list to specify their fallback preferences and there's no need to enforce it.

Therefore this method isn't really necessary and will be thus removed.
