Cleanup of outdated policykit packages

[musca]

Hello,

last year we had an incident with broken policykit and I just found out, debian still uses lower version numbers than our temporary fix package. (Higher versions from experimental didn't make it into unstable during the whole time.) 
Let's downgrade to the newest version from debian unstable.

root@sidbox:~# dpkg -l | grep 0.112-5.3.1~really-0.105-8  # lists packages of outdated version number
ii  gir1.2-polkit-1.0                                   0.112-5.3.1~really-0.105-8           amd64        GObject introspection data for PolicyKit
ii  libpolkit-agent-1-0:amd64                           0.112-5.3.1~really-0.105-8           amd64        PolicyKit Authentication Agent API
ii  libpolkit-backend-1-0:amd64                         0.112-5.3.1~really-0.105-8           amd64        PolicyKit backend API
ii  libpolkit-gobject-1-0:amd64                         0.112-5.3.1~really-0.105-8           amd64        PolicyKit Authorization API
ii  policykit-1                                         0.112-5.3.1~really-0.105-8           amd64        framework for managing administrative policies and privileges

root@sidbox:~# dpkg -l | awk '/0.112-5.3.1~really-0.105-8/ {print $2"=0.105-15"}'  # print test output with current version appended
gir1.2-polkit-1.0=0.105-15
libpolkit-agent-1-0:amd64=0.105-15
libpolkit-backend-1-0:amd64=0.105-15
libpolkit-gobject-1-0:amd64=0.105-15
policykit-1=0.105-15

root@sidbox:~# apt-get install $(dpkg -l | awk '/0.112-5.3.1~really-0.105-8/ {print $2"=0.105-15"}')   # downgrade packages

Well, we are back to business and will get updates from unstable in the future.
