Exit with failure during QFramework.BREAK

Release notes

Fixed an issue in which the CAFExample CI would not report a failure when QFramework.BREAK was triggered while executing the analysis runtime python scripts. The CAFExample CI should now correctly report a job failure upon encountering QFramework.BREAK

This MR fixes an issue which was first encountered in this CAFExample CI job: https://gitlab.cern.ch/atlas-caf/CAFExample/-/jobs/1248255

The CI would still finish successfully even if encountering a QFramework.BREAK in one of the runtime analysis scripts. The fix is to simply exit with 1 instead of 0.

The CI now correctly fails when encountering QFramework.BREAK: https://gitlab.cern.ch/atlas-caf/CAFExample/-/jobs/1246549
