    Replace mox with mock for xenapi vm_utils.lookup
    
    The py34 check jobs are failing occasionally when trying to use mox on
    the vm_utils.lookup method, seemingly because it is not restored
    properly at some point. Rather than chase that down this patch replaces
    the usage of mox with mock for patching this method.

  This failure has happened to me a few times now on Jenkins jobs but does not reproduce locally. I suspect an ordering issue in the tests, especially since it's not always the same method that fails.
