gnuradio-examples, gr-audio: moved audio Python and C++ examples into gr-audio
This begins a transition of examples from a separate gnuradio-examples component
into an examples directory with the component they go with. In this commit:
gnuradio-examples/c++/audio/ => gr-audio/examples/c++
gnuradio-examples/python/audio => gr-audio/examples/python
The system installation directory remains $PREFIX/share/gnuradio/examples/audio
