repart: correctly handle "uninitialized" machine-id

Browse Source 
When systemd-repart runs from initramfs, it reads out /etc/machine-id
from the rootfs as a seed for partition UUIDs.  However, the machine-id
could be in an "uninitialized" state from a previous failed first boot.
In this situation the -ENOMEDIUM code-path (no machine-id set) should be
taken.
