Add a pick first rule. (#105)

NOTE(kudo): sometimes cmake will bundle linked dependencies. when the issue happens, there are build errors like this:

```
Execution failed for task ':react-native-v8:mergeReleaseNativeLibs'.
> A failure occurred while executing http://com.android.build.gradle.internal.tasks.MergeJavaResWorkAction
   > 2 files found with path 'lib/arm64-v8a/libv8android.so' from inputs:
      - /path/to/app/android/node_modules/react-native-v8/android/build/intermediates/merged_jni_libs/release/out
      - /path/to/app/android//node_modules/react-native-v8/android/build/intermediates/cmake/release/obj
```

since the error happens inside react-native-v8 where it under our control, it's safe to pick any libv8android.so.
