Ticket 47968 - Fix for issues with multiple log backends

Bug Description:

* Did not correctly use str formats in the output to journald_print
* Due to a change strcmp api, the values were not checked properly
* The default template did not have the correct backend value

Fix Description:
* Correctly use string formats to avoid compilation errors
* Fix the check for values of strcmp
* Fix the template to include dirsrv-log
* The rpm spec to include the correct systemd libraries
