jsoninfo: add inventory-artifacts cli, which stops after artifacts-reduced and adds kernels.ndjson and uboots.njdson via jq

• jsoninfo: add inventory-artifacts cli, which stops after artifacts-reduced and adds kernels.ndjson and uboots.njdson via jq
  • if one runs ./compile.sh inventory-artifacts we shall get:
    • output/info/kernels.ndjson: one line for each kernel build
    • output/info/uboots.ndjson: one line for each u-boot build
  • this is meant as base for other tooling that acts "for each kernel" or "for each u-boot" such as patch/config rewrites, etc

.ndjson is fine, but still requires read / jq-fu to process. I'll look into outputting something that bash can loop better over.
