silverblue: build from Everything repo

There are several recommends packages that aren't getting installed in
Silverblue because the workstation comps group doesn't include them.
One of these is slirp4netns which is needed for rootless containers
using podman.

Since we are thinking about removing the separate Workstation repo
anyway[1], then maybe we can just move SB over to the Everything repo.
