[PATCH v5 08/12] tests/acceptance: wait() instead of shutdown() where appropriate

[John Snow]

When issuing 'reboot' to a VM with the no-reboot option, that VM will
exit. When then issuing a shutdown command, the cleanup may race.

Add calls to vm.wait() which will gracefully mark the VM as having
exited. Subsequent vm.shutdown() calls in generic tearDown code will not
race when called after completion of the call.
