This fronts the functionality currently implemented in rpm-ostree,
for the same reason as we have `build-rootfs`; the functionality
may move elsewhere in the future.

While "cross builds" and using a separate repos container can
feel very clean (instead of mutating the builder container)
it's actually much closer to our default intention to support building
a new version of the base image from the image itself.
So make the source root optional (i.e. it defaults to `/`).
This will improve the default UX, but also more specifically
will fix the issue that cachi2 breaks the separate source root flow.

- Embed the manifests into the container image
- Add bootc-base-imagectl which is a tightly controlled frontend
to execute on those manifests.
For now, we don't attempt to rework how we build the standard
image to actually look like `dnf install`, but we show that
it can work.
