    Allow child OperationDetails to emit error capture callback too (#790842)
    
    Just copies the callback into each newly added child detail.  As there
    are no more uses of set_success_and_capture_errors() yet, libparted
    errors are still only captured once at the top-level of each operation.
    
    Bug 790842 - Report libparted messages into operation details at the
                 point at which they occur
