android_webview: fix to avoid 64-bit blacklisting.
Currently the chromium code is blacklisted for 64-bit builds in Android
which makes testing our 64-bit build support difficult. In order to
remove this blacklist entry we need to make sure that non-native-code
build targets refer to the 32-bit output directories, since the 64-bit
ones won't exist in all configurations yet.
We can revert this change once we have full 64-bit build support.
