Bug 1411589 - Notify flatpak print portal that print to file has finished, r=stransky

Browse Source 
The GTK print portal is notified by the observer service with 'print-to-file-finished'
topic. The print filename is used as an identifier of the target in case multiple
printing jobs are in progress.
