Adding cfg for ubuntu proper naming convention!

[Anushree-Mathur]

After adding this we can run all our ubuntu tests with the following qcow2 as naming convention with ubuntu-25.10-ppc64le.qcow2 and python command can be run as:

python3 avocado-setup.py --run-suite guest_cpu --guest-os Ubuntu.25.10.ppc64le --only-filter 'virtio_scsi virtio_net qcow2' --no-download
