    security/vuxml: notify polkit local-privilege-escalation

    It was unclear if the actual explot would work on FreeBSD,
    since there's no GNU libc which the payload would work on.
    The following changes are / have been applied:
    - fix in polkit from upstream (from Greg V)
    - at kernel level, fixes to disallow argc==0 (from kevans, I think)
