[Android] Fix core shell crash issue after rebasing to Chromium35

icu_use_data_file_flag has been enabled on Android after Chromium35.
Need to package icudtl.dat resource.

TODO:
1. Does xwalk need this flag opened? the data has size of 5.6M.
2. Will also be crashed on Shared mode, caused by application context issue.
