Update postmortem metadata jobs

This commit updates the jobs for generating postmortem
metadata. I96a8a7cdded6f7c37b6f1da659d63df9e3a5de2b moved
the Code class to a new file without updating the postmortem
jobs. This resulted in some constants used by Node.js to
disappear, leading to build failures on SmartOS.
