Host preparation steps which are deliberately skipped when
pretend-creating a commandline are normally executed after VM object
preparation. In the test code we are faking some of the host
preparation steps, but we were doing that prior to the call to
qemuProcessPrepareDomain embedded in qemuProcessCreatePretendCmd.
By splitting up qemuProcessCreatePretendCmd into two functions we can
ensure that the ordering of the prepare steps stays consistent.
