osinfo: Add OpenSUSE Tumbleweed data

Tumbleweed is a rolling release variation of OpenSUSE and since its
Osinfo data does not describe it as a derivative of a stable version,
Boxes doesn't pick the OpenSUSE logo for Tumbleweed.

This doesn't happen for Debian Testing because it derives and
upgrades from a stable Debian release.
