Unable to use "docker cp", but it worked 2 days ago

@kimh Thank you for providing the patched version! It doesn’t work for our build unfortunately because our setup uses docker-compose 1.5, which requires docker >= 1.9. Any chance you can also provide a patched version of 1.9.1, which was introduced in this thread:

Alternatively, I can look into a solution similar to the one @Alino provided. We might be able to use tar or another utility to get the files out of the container.
