mctp-demux-daemon: Use systemd socket activation
Take advantage of lazy initialisation.
However, this also allows (one) daemon providing services over MCTP
(pldmd) an opportunity to start prior to MCTP interfaces coming up. This
is a stunted way to provide capabilities that might be assumed by other
components (the host) without implementing some required messages from
the MCTP standard.
