core: Add machine-id setting
Allow for overriding all other machine-ids which may be present on
the system using a kernel command line systemd.machine_id or
--machine-id= option.
This is especially useful for network booted systems where the
machine-id needs to be static, or for containers where a specific
machine-id is wanted.
