Set Suse family for openSUSE Tumbleweed & Leap

On openSUSE Tumbleweed, lsb-release -a currently reports
the distributor ID as "openSUSE Tumbleweed". On openSUSE
Leap, the distributor ID is "SUSE LINUX".

Add them to the OS_FAMILY dict as Suse family systems.

Also add an entry to TESTSETS in test_distribution_version.py
for openSUSE Tumbleweed.
