contrib: Remove deb,rpm packaging

These have been bitrotting for a while now (the deb version lists
version 0.9.90), and we have no mechanisms for building, deploying or
testing these packages. The primary mechanism for distributing and using
Cilium is via docker images, so let's focus on making those work really
well and discard these. We can always resurrect these in future via git
if we need to.
