hostname.py: Fix openSUSE distribution name (#47020)

All openSUSE distributions changed to the way they are returned from distro.id().

This patches fix the openSUSE Leap and SLES distro names, and adds one entry for Tumbleweed.

These descriptions are capitilized, as expected by Ansible's hostname module.
