NETOBSERV-1595: generate BPF from CI

[jotak]

• Add BPF generation steps in the main Dockerfile
• Split make generate in 2 (one for BPF another for protoc ; we don't need to build protobuf from CI as this is still code)
• Add a pull-request check to verify that the provided BPF bin match the code

I intentionally removed the .o files from source and generated a build just to make sure it uses CI-generated .o I'll put back .o in git so that they are still available for local runs.

@msherif1234 one downside of this is increased image build time, that can perhaps be painful when you build locally. If this ends up too painful we could create a separate dockerfile for local builds, that would diverge from CI dockerfile.
