debug symbols for package docker-registry

 The Docker toolset to pack, ship, store, and deliver content.
 .
 The Docker Registry 2.0 implementation contained in this package is for storing
 and distributing Docker images. It supersedes the docker/docker-registry
 project with a new API design, focused around security and performance.
 .
 This project should provide an implementation to a V2 API for use in the Docker
 core project. The API should be embeddable and simplify the process of securely
 pulling and pushing content from docker daemons.
 .
 The new registry implementation provides the following benefits:
 .
  * faster push and pull
  * new, more efficient implementation
  * simplified deployment
  * pluggable storage backend
  * webhook notifications
