use libreoffice.jar to fix FTBFS with LibreOffice 7.x
As described in https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=964706
- juh.jar
- jurt.jar
- ridl.jar
- unoil.jar
are now dummy packages having Class-Path: libreoffice.jar.
As that somehow is not picked up and a change like https://gerrit.libreoffice.org/c/core/+/98929 does not work (at least here, maybe I did something wrong when hacking it into the poms...) either...
Let's just use libreoffice.jar.
Regards,
Rene
