Zbigniew Jędrzejewski-Szmek 2ff40c758e update-done: add --root= arg ...

The idea is to use this when building an image to mark the image as not
needing updates after the reboot. In general it is impossible to say if
any of the early boot update services can be safely skipped, except when
the creator of the image knows all the contents there and has made sure
that all the updates have been processed. (This is in fact what happens
in a typical package-based installation: the packages have scriptlets which
implement the changes during or after the installation process.)

With this patch, the image build process can do 'systemd-update-done --root=…'
at the appropriate point to avoid triggering of ldconfig.service,
systemd-hwdb-update.service, etc.

I didn't write --image=, because it doesn't seem immediately useful. The
approach with --root is most useful when we're building the image "offline",
which means that we have a directory we're working on.
