util/docker/coreboot-sdk: Do system update before installing packages

Even if the Debian Sid image is probably updated frequently, the
existing packages should be updated before installing new ones. So
update the base image in advance.

Also, while on it, add a step to remove superfluous packages by
running `apt-get autoremove`.
