[Ubuntu] python files are present twice

After installation of the new zvmsdk package on Ubuntu, the whole python hierarchy is present twice, once in /usr/lib/python3, and once in /usr/lib/python3.12.

For example:

mikef@feilong:~$ dpkg -L grep zvmsdk | grep grow_root_volume.j2 
/usr/lib/python3/dist-packages/zvmsdk/vmactions/templates/grow_root_volume.j2 
/usr/lib/python3.12/dist-packages/zvmsdk/vmactions/templates/grow_root_volume.j2

There's probably a symlink present at packaging time, with this as effect.

It has no bad consequence other than lost space & making debugging trickier.
