Merge ~xnox/launchpad:kernel-ubuntucore-cpc-ppas into launchpad:master

Avoid expiring PPAs related to building UC kernel snaps and CPC images

Some UC kernel snaps are built from PPAs owned by the kernel team.
Some CPC / Cloud kernel previews are build from these PPAs too.

It is best to keep those PPAs unexpiring. The set of PPAs does change from time to time, hence keeping them all.

This is potentially a lot of very large PPAs. I'd rather be more selective if at all possible.

[Dimitri John Ledkov (xnox)]

Ok, I will check which ones don't make to the Ubuntu Archive proper ever, and limit to at least those.

[Dimitri John Ledkov (xnox)]

Updated the list to just two PPAs.

The packages inside them have been built/routed via private signing PPA, thus there should not be much additional overhead from keeping these around.
