Fix the sandbox build & get rid of ICU dependency.
Changed package name from com.android.inputmethod.latin2 to com.google.android.inputmethod.latin2.
Copied LatinIME's current dictionaries from master's vendor directory.
Confirmed latin_tolower() function returns the result identical to ICU's u_tolower().
- Note that I will merge the ICU dependency removal change to master.
