[baseimage]: add docker ps to the sudoer file

[arlakshm]

Signed-off-by: Arvindsrinivasan Lakshmi Narasimhan arlakshm@microsoft.com

fixes sonic-net/sonic-utilities#1389
- Why I did it
With the recent changes in sudoer files. The show commands fails for the read-only users.
The problem here is the 'docker ps' is failing in the function get_routing_stack() therefore all the CLI commands are failing.

- How I did it
add docker ps to the sudoers file

- How to verify it
Verify the show commands works for read-only users
