Adam Williamson d07b5a4178 Tweak ostree build and rebase for update tests to be more robust
We have had several problems where rebasing from one release to
another just doesn't work, and we have to work around it somehow.
Sometimes it's difficult or impossible to do. All we want to do
here is check the rebase mechanism itself; we don't actually want
to assert that you can rebase to any specific other release.

For update tests, we should be able to use a non-standard ref
name for the ostree we build, embed into the installer image,
and install. That should mean we can then rebase to the standard
ref name for the same release, which should be much safer than
trying to rebase to a different release. We can't do this for
the compose tests, but at least for update tests I'm hoping this
makes things more robust.
