Subject: [PATCH] stellarium: add passthru.tests.version

Add a passthru test to stellarium to verify it can be started and print
its version.

The test runs stellarium with a temporary home directory
using xvfb-run, since stellarium requires a writable home directory and
cannot be run in headless mode.
