test: shutdown the machine on fail after soft-reboot

Since the soft-reboot drops the enqueued end.service, we won't shutdown
the test VM if the test fails and have to wait for the watchdog to kill
us (which may take quite a long time). Let's just forcibly kill the
machine instead to save CI resources.
