Fixes for when using clang/llvm as CC/CXX

Enhance check for presence of static-libstdc++

* Clang does not generate code to initialize the entire union when
  initializing a nested struct. This is the case for union bpf_attr.
  As a workaround, call memset explicitly.

Add proper debian build support, rename libbcc.so

improve examples using new features

This adds support for properly tagging the build when cmake is run not
in a git tree, which is the case when building from src-deb.
Signed-off-by: Brenden Blanco <bblanco@plumgrid.com>

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.
