Prep for making `--unified-core` the only path. It turns out our compose testsuite has a lot of hardcoded ideas about how the two paths work. The rojig tests in particular need cached RPMs, so we can't just rely on caching the pkgcache repo. Add a `--download-only-rpms` that always returns RPMs, and doesn't import into the pkgcache repo.
