Truncate /etc/machine-id instead of deleting it.
If /etc/machine-id exists but is empty, systemd will do tricks
with bind-mounts to ensure that a valid transient UUID is bind-mounted
over it, which is exactly what we want for a live system.
If /etc/machine-id does not exist, systemd-journald
will just fail, which is undesirable.
