Martin Gräßlin 6d60f01ad9 Skip DontCrashEmptyDecorationTest if we don't have a /dev/dri/card0 device
Without the /dev/dri/card0 mesa fails to initialize egl and the test
fails. In order to silence the failure till the system provides the
device file, we better skip the test.

A nullptr crash in that case is fixed in WaylandServer tear-down.
