avoid file conflict in debian-menus package (fdo#67031)

Use versioned file name for Debian specific /usr/lib/menu/libreoffice.

All the other files have been versioned for years when we did this
for RPMs. Heh, nobody noticed this with DEBs because people were
used to that conflict and did not complain ;-)
