sphinx: set up the examples so they show up in the generated doc

This tweaks the conf.py.in config so that examples shows up in the
examples section of the doc.

Note: These are examples, not tools, as tools are deployed, and
examples are not. Since they are not deployed, just call them
examples. Also include iio_info to the list.
