'qemuBackupJobTerminate' needs the API flags to see whether VIR_DOMAIN_BACKUP_BEGIN_REUSE_EXTERNAL. Unfortunately when called via qemuProcessReconnect()->qemuProcessStop() early (e.g. if the qemu process died while we were reconnecting) the job is cleared temporarily so that other APIs can be called. This would mean that we couldn't clean up the files in some cases. Save the 'apiFlags' inside the backup object and set it from the 'qemuDomainJobObj' 'apiFlags' member when reconnecting to a VM.
