    qcow2: Pick random port in range
    
    I'm working changing rpm-ostree to spawn VMs in parallel, and
    currently this races because we release the socket, then start
    qemu.
    
    I have a plan for a reliable fix, but even with that let's use a random port
    since it makes collissions a lot less likely.
