Required so that the Python readline and curses stdlib modules will be built, now that libreadline-dev is intentionally no longer in the Heroku-24 build image: https://github.com/heroku/base-images/pull/296

(These headers are only needed when the Python runtimes are being compiled. The run image still has the necessary runtime library counterparts.)
