machined: split out machine registration stuff from logind
Embedded folks don't need the machine registration stuff, hence it's nice to make this optional. Also, I'd expect that machinectl will grow additional commands quickly, for example to join existing containers and suchlike, hence it's better keeping that separate from loginctl.
