[FIX] conf.py: check odoo_dir is a real Odoo sources dir

In `conf.py`, we try to find a Odoo sources folder among `odoo` and
`../odoo` directories without really checking that they really are
Odoo sources folders, leading to doc generation error if it's not the case.

So, to improve that, this commit checks that the selected Odoo sources folder
contains `odoo-bin`.

While we're at it, the logging is also improved to always display the
matching odoo sources' folder and version.

closes odoo#1340
