[IMP] 12.0 base_report_to_printer: improve job title

instead of sending a temporary random file name as the title of the job,
use the report file name. Since this is not displayed by default by
cups, document how to configure the CUPS server so that the information
can be displayed.

Clean up the temporary file after printing to avoid cluttering the
server in the long run.

+The jobs will be sent to the printer with a name matching the print_report_name

+displayed by CUPS web interface or in Odoo. To see this information, you need
+to change the configuration of your CUPS server and set the JobPrivateValue
+directive to "job-name", and reload the server. See `cupsd.conf(5)
