feat: Refine the image

* Use latest fedora instead of centos as centos is dead :(
* Install the newest map pack from AIArena.
* Run SC2 under unprivileged user for security.
* Reduce count of intermediate volumes and do additional cleanup.
* Move port option to CMD to support usage of different port.
