Add 7 Days to Die dedicated server container; drop V-Rising

Browse source 
Enables the previously-disabled game-servers module with a new 7DTD
container (vinanrra/7dtd-server) on ports 26900 TCP + 26900-26902 UDP.
A oneshot systemd service waits for LGSM's first install to drop
sdtdserver.xml, then patches in the server name, password, and
random-gen world before restarting the container. V-Rising is removed
— the module hadn't been imported, so this just drops dead code.
