It seems that this strategy doesn't work well when the user runs
`pip install .` in the `bindings/python-cffi` directory.

Apparently all the files are copied to a temporary directory first:

https://travis-ci.com/github/pazz/alot/jobs/351377760#L708-L710

It doesn't happen with the original bindings, probably because the version
number is stored in `bindings/python/notmuch/version.py`, which is also
copied when `pip` runs.
