When populating CMD, do not include Entrypoint

Browse Source 
Previously, we use CreateConfig's Command to populate container
Command (which is used as CMD for Inspect and Commit).
Unfortunately, CreateConfig's Command is the container's full
command, including a prepend of Entrypoint - so we duplicate
Entrypoint for images that include it.

Maintain a separate UserCommand in CreateConfig that does not
include the entrypoint, and use that instead.

Fixes #3708
