vm: 'system-docker-image' provides an entry point.
This simplifies use of images created with 'guix system docker-image'. * gnu/system/vm.scm (system-docker-image)[boot-program]: New variable. [os]: Add it to the GC roots. [build]: Pass #:entry-point to 'build-docker-image'. * gnu/tests/docker.scm (run-docker-system-test): New procedure. (%test-docker-system): New variable. * doc/guix.texi (Invoking guix system): Remove GUIX_NEW_SYSTEM hack and '--entrypoint' from the example. Mention 'docker create', 'docker start', and 'docker exec'.
