Remove unused module index in documentation

We don't currently use sphinx.ext.autodoc as most of the source code
is missing docstrings anyway. Remove it so that we'll stop creating
a broken link to py-modules.html when rendering documentation. This
can be reverted later when we're ready to add source documentation
to the project.
