Subject: [PATCH] doc/python-cffi: import from built bindings, not installed
 module

Previously the python-cffi bindings either failed to build, or built
for the wrong module by using the installed module.

The fix requires correction the module path, building the bindings
before docs, and helping python find the built libnotmuch.

Based on patch / discussion from Micheal Gruber [1]
