blockjob: expose error string via query
When we've reached the concluded state, we need to expose the error state if applicable. Add the new field. This should be sufficient for determining if a job completed successfully or not after concluding; if we want to discriminate based on how it failed more mechanically, we can always add an explicit return code enumeration later. I didn't bother to make it only show up if we are in the concluded state; I don't think it's necessary.
