Fixed an improper access control vulnerability in systemd-machined service. The RegisterMachine D-Bus method did not properly validate the class parameter, allowing local unprivileged users to potentially execute arbitrary commands with root privileges. This patch rejects invalid class types when registering machines, ensuring only MACHINE_CONTAINER and MACHINE_VM classes are accepted.
