Markus Hilger fc63269dc7 Give every deployed node its own machine-id ...

Captured images carried the machine-id of the source system, and images
built with imgutil carry the one generated in the build root, so every
node deployed from a profile shared it. That breaks anything keyed on it,
such as DHCP DUIDs and journal identities.

Capture now stores an empty /etc/machine-id. Diskless boot on EL and SUSE
writes a stable per-node one derived from the node name and the DMI
product UUID, as Ubuntu already does, using openssl since the initramfs
has no sha512sum. Install to disk copies that machine-id into the target
and renames the boot loader entries from the image to it. Otherwise
kernel-install in post.sh adds a second set of entries under another ID.
