Android,Windows: support long paths in tooling

aar_resources_extractor now supports long paths
on Windows.

If the script needs to extract a file from the
AAR where the destination path is too long, the
script will:
1. create a temporary junction under a short path,
   pointing to the destination directory (which
   has a long path)
2. extract the file under the junction
3. delete the junction and the temp directory
