This document was written with SPDX 3.0 in mind (create-spdx-3.0 class)
on OE-Core's master, but Scarthgap only supports SPDX 2.2
(create-spdx-2.2).
The create-spdx-2.2 class only generate a tar.zst output, so remove the
other outputs listed here.
Also, ancillary outputs are not only deployed in tmp/deploy/spdx/MACHINE
but tmp/deploy/spdx in general.
