[Do not merge] Update docker image with driver permissions

[Agustin Alba Chicar]

Update the base Dockerfile adding permissions to the file /dev/dri/card0 to the user gazebo.

I've found these links which explains the source of the problem with Intel drivers in the following link:

• http://wiki.ros.org/docker/Tutorials/Hardware%20Acceleration
• This video shows how the --device argument works with Intel drivers: https://www.youtube.com/watch?v=GsLZz8cZCzc&feature=youtu.be
• https://docs.docker.com/engine/reference/run/ --> Explains how --device works

So the way to go is to add the --device /dev/dri when using Intel drivers.
