complete-artifact-matrix: fail when an image chunk is missing

jq ran inside an echo argument, so set -e did not see its failure.
A missing chunk or matrix file then gave empty outputs, and the image
jobs skipped those chunks without an error. Assign the jq results
first and use jq -e for the chunk.
