    tests/acceptance: Don't test reboot on cubieboard
    
    cubieboard does not have a functioning reboot, it halts and QEMU does
    not exit.
    
    vm.shutdown() is modified in a forthcoming patch that makes it less tolerant
    of race conditions on shutdown; tests should consciously decide to WAIT
    or to SHUTDOWN qemu.
    
    So long as this test is attempting to reboot, the correct choice would
    be to WAIT for the VM to exit. However, since that's broken, we should
    SHUTDOWN instead.
    
    SHUTDOWN is indeed what already happens when the test performs teardown,
    however, if anyone fixes cubieboard reboot in the future, this test will
    develop a new race condition that might be hard to debug.
    
    Therefore: remove the reboot test and make it obvious that the VM is
    still running when the test concludes, where the test teardown will do
    the right thing.
