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.

This is needed to force the rebase on current CoreOS (because it
has zincati registered by default). It should be harmless in all
other cases.

There's a weird issue with the rpmostree_rebase test for this
update:
https://bodhi.fedoraproject.org/updates/FEDORA-2023-f6afa6f9e5#comment-2919613
it doesn't reproduce locally (I can type fine after doing the
same things the test does up to the rollback) and I can't think
of any possible cause, and I don't want to hold the update up.
So we're just gonna work around it and hope this doesn't start
happening to all F38 update tests after this goes stable. If it
does, we'll have to do the workaround for all of them.
The workaround is just to rollback and reboot 'blindly', instead
of checking the rollback command works. The drawback is that if
the rollback command fails we'll wait 7.5 minutes before giving
up on it, and it'll be a bit less clear exactly what happened.

This makes the two rpm-ostree tests written for IoT - overlaying
and rebasing - work across all rpm-ostree-based flavors we
currently test (IoT, CoreOS and Silverblue) and runs them on
all those flavors.
This requires some other changes. For the Workstation ostree
installer update tests, we have install_default_update_ostree
upload a disk image and run these tests on that image. That means
install_default_update_ostree cannot use a scratch disk (as if
we boot it with two disks but only upload one, the subsequent
tests fail to boot, looking for the missing second disk), but its
specified disk size should be large enough for all updates.
