Current code changes /etc/sudoers, which belongs to sudo. If you use this image as a base and somehow have to update sudo, it asks if you want to keep /etc/sudoers or overwrite it with the default file. The build then fails cause there is no user input. This patch will change the behavior: it will create a file named /etc/sudoers.d/neon, which is included by the /etc/sudoers provided by sudo.
