    Try to set MACHINE so machine in `utils/setup_worker.sh` is honoured
    
    There exists a `qemu_x86_64` machine defined in the OpenQA web UI. I
    prefer to ignore this and have the machine config committed to Git
    along with the tests. Hopefully setting `MACHINE` explicitly will
    achieve that.
