Description

bin/jenkins/finalize.sh does a variety of diagnostic things like resolving minidumps and dumping system information. If some permissions are missing, dmesg can fail, and that will cause finalize.sh to exit early. In this case, minidumps won't get resolved.

finalize.sh should be resilient to failures in any individual command, so that it continues with as much diagnosis as it can. A failing dmesg is not worth failing over.
