Subject: [PATCH] appliance: init: generate /etc/machine-id

Some of the systemd-tmpfiles snippets need the machine ID of the running
system; the current lack of this file produces warning messages during
the appliance boot like:

[/usr/lib/tmpfiles.d/systemd.conf:26] Failed to replace specifiers: /run/log/journal/%m
[/usr/lib/tmpfiles.d/systemd.conf:28] Failed to replace specifiers: /run/log/journal/%m
[/usr/lib/tmpfiles.d/systemd.conf:29] Failed to replace specifiers: /run/log/journal/%m

Thus create a new randomly-generated /etc/machine-id on boot.

(cherry picked from commit 807433bc230987270680ad28643e9c1741790c29)
