    Set remove-machine-id to executable

    We had previously added an element to remove the machine id from the
    images however the script is not executable so it wasn't actually being
    run as part of the image building process. This change sets
    70-remove-machine-id to be executable so that /etc/machine-id will
    actually be removed from the images during the building process.
    Additionally this changes the element to clear the file rather than
    delete it as if the file is missing, things may not work as expected.

    element remove-machine-id has been added to tripleo-common in stable/ocata
    and we are experiencing strange issues related to missing /etc/machine-id

    Closes-Bug: #1719421
