Useful skiboot artefacts are not copied to output directory

[shenki]

When building we end up with skiboot.lid and skiboot.lid.bin.

Ideally we would end up with skiboot.elf, and skiboot.lid.xz for p8, or skiboot.lid.xz.stb for p9.

I see skiboot.elf and skiboot.map included as part of output/images/host_fw_debug.tar.

It gets weird here.

So, we assemble a skiboot.lid.xz as part of building skiboot - we build with xz -9 and CRC32. It turns out that update_images.pl in the pnor/ repo constructs its own compressed skiboot with the default xz compression level (6). So the skiboot build artifact is not being used.

Additionally, even though we produce the secure boot header with the imprint keys, the genPnorImages.pl script in the hostboot repository is what generates the secureboot header for the skiboot.lid that ends up in the PAYLOAD partition (via scripts in the pnor repo).

I'll assign this to myself as I'm reworking the trainwreck that is PNOR assembly currently and this issue should be resolved as a side-effect of it.
