Fix CI to avoid RedoxFS/FUSE/tar problems

I have not tested these fixes in their entirety because it will take all day to do a fresh build on a clean system. I will start the test shortly.

Writing binary packages to RedoxFS/FUSE from tar-rs is causing EIO, which is causing the installer to stop. This fix will cause the binary packages to be rebuilt entirely and avoid using pkgutils/tar-rs. vim is removed from the demo because it fails to build some of the time.
