Subject: [PATCH] scripts/make-dockerfile.sh: tweak sha256 sum handling

Drop the spurious cat, we already echo the value the like above so it's
pretty clear what it is in the logs.

While here, rename the file to the what's commonly used by us (see the
ISOs) and others, while removing the misleading "rootfs.tar" - we're
having a tar.zst tarball.
