ukify: show .sbom sections as binary

ukify: show .sbom sections as binary

Fixup for e87dec82bec6eff015b368b3c746810d684fc6af:
I misunderstood the format. It's actually CBOR, i.e. some binary format.
When trying to show show text we would first check if it's valid UTF-8,
so we would handle this gracefully, i.e. emit a warning and not print
the contents.
