    puppet: cobbler: Fix CentOS version detection

    Recently, CentOS released version 7.3.1611, which triggered a latent
    bug in fuel-library puppet scripts related to differentiating between
    6.x and 7.x major versions: 7.3.1611 is wrongly detected as 6.x,
    leading to the wrong packages being attempted to be installed,
    leaving nailgun server service broken on the Fuel Master node.

    This change forces the match at the beggining of the version string
    (e.g. "/^6.+/: {" instead of "/6.+/: {"), so the new CentOS 7.3.1611
    no longer matches the condition for 6.x).

    Closes-bug: 1649895
