[PATCH] UBUNTU: [Packaging] Do not allow update-version-dkms to be run on a derivative kernel

[Tim Gardner]

It is too easy to run this script when drifting through the cranky cheat sheet
without really thinking about what you're doing while cranking a derivative
kernel.

v2 - use debian.DERIVATIVE/etc/update.conf to determine if this is a master
     dependent derivative.
