Support Crosswalk and Android System WebView in the same application

xwalk will put icudtl.dat in different folder like raw/res instead of
assets.So it's not right to check and read from assets/icudtl.dat in
high priority.Otherwise when android webview is called , app will
extract webview.apk and copy it's icudtl.dat to assets,hence the two
icudtl.dat will conflict.
