Add proper debian build support

The cmake based build system is nice, but not quite production ready.
Move to the more painful but featureful debuild style. This is one step
towards an upstreamable package.

Rename libbpfprog (ugh) to libbcc.

Split out python-bpf and libbcc-examples into separate packages that
depend on libbcc.
