Error in xfce-test start for arch based distros

[stergem]

The error is related to /etc/timezone and fails to start.
It starts if line 489 DOCKER_MODES="${DOCKER_MODES} --volume /etc/timezone:/etc/timezone" in xfce-test.sh is commented out. Don't know if there is any functionality loss.

Shouldn't be a problem to comment it out. In the archlinux support PR, I have added a simple if-statement in the xfce-test that should handle this issue.
