When running `docker login` or `docker logout`, the CLI updates the configuration file by creating a temporary file, to replace the old one (if exists). When using `sudo`, this caused the file to be created as `root`, making it inaccessible to the current user. This patch updates the CLI to fetch permissions and ownership of the existing configuration file, and applies those permissions to the new file, so that it has the same permissions as the existing file (if any). Currently, only done for "Unix-y" systems (Mac, Linux), but can be implemented for Windows in future if there's a need. Signed-off-by: Sebastiaan van Stijn <github@gone.nl>
