Cleanup comments/docs in backend_macosx, backend_pdf.

We don't bother with the staple comments about pylab integration in
other backends, so remove them from backend_macosx

It seems better to let FigureCanvasMac and FigureCanvasPdf just inherit
the parent docstrings (and move comments about implementation details of
FigureCanvasMac to, well, comments).
