Set runAsUser for Container

Follow the instructions from "Discovering and Using USB Cameras" (https://docs.akri.sh/demos/usb-camera-demo) using microk8s and the akri-video-streaming-app container fails to start. The error is caused by the container is running as root and the setting in deployment specifies "runAsNonRoot=true", see the output below:

I think it would be better to change these containers to effectively run as non-root rather than allowing them to do so, I don't see any reason for this one to run as root.

Set runAsUser to run the container as non-root.
