Provide the full CMSSW exit code from the job report (if possible)
We currently use `condor_chirp` to report the Linux-provided exit code from CMSSW:

https://github.com/dmwm/WMCore/blob/0615bd977edd4ad103db7ea24f461aa794c9a104/src/python/WMCore/WMSpec/Steps/Executors/CMSSW.py#L236

However, this is an 8-bit exit code: CMSSW's framework job report provides a more detailed exit code.

If the exit code is non-zero, the framework job report exists and is parseable, we should provide the error code from CMSSW instead of the one from Linux.
