Remove dbus from startup in Dockerfile

The change in the Dockerfile for firewalld removes the activation of dbus at startup. It is not necessary to enable dbus in the Dockerfile since the host system is already running a dbus instance. This simplifies our Dockerfile and reduces potential for conflicts or errors.
