Remove run-as-user command because it is also the entrypoint

[dagomar]

I found that when using the provided shell scripts the docker container fails to run the desired command. Instead the command that is send to the container is:

/run-as-user /run-as-user /usr/local/bin/{script} [...]

I was able to see with 'top' that the above was the command which was running without ever finishing. Removing the /run-as-user from the shell scripts worked for me. I have created a pull request with the changes:

#140

Done!
