build system: Check that python bindings have consistent version when releasing

Thanks to Sebastian Spaeth breaking out version.py, this can be done
without loading notmuch.py, or using sed. version.py is not (yet)
autogenerated because it seems more important to minimize the
differences between the tagged version and the tarball.
