This helps ensure that `github.com/docker/docker/pkg/...` is actually safe to use in isolation (ie, doesn't import anything from `github.com/docker/docker` except other things from `pkg` or vendored dependencies).
Adding `github.com/docker/docker/utils` to the imports of `pkg/version/version.go`:
```
---> Making bundle: validate-pkg (in bundles/1.7.0-dev/validate-pkg)
These files import internal code: (either directly or indirectly)
- pkg/version/version.go imports github.com/docker/docker/autogen/dockerversion
- pkg/version/version.go imports github.com/docker/docker/utils
```
And then removing it again:
```
---> Making bundle: validate-pkg (in bundles/1.7.0-dev/validate-pkg)
Congratulations! "./pkg/..." is safely isolated from internal code.
```
