Any recent shim will refuse starting an image that does not have an sbat section and will do so with a generic "Security Violation" message. And it is very easy to forget passing -Dsbat-distro=auto to meson when creating a fresh build dir. Adding sbat info when shim is not used or secure boot is disabled does not hurt anyone, so default to auto. This still ensures to not add auto-detected info in case we are cross building.
