Security list cleanup

FYI, Due to some error in the lists, some people might have been auto-subscribed to the security(a)ovirt.org list, while others were already subscribed without a reason (possibly spam joining by accident). If you were unsubscribed and feel you should remain on the list, please contact me in private with the justification.
