python-setuptools-rust: Set cargo profile from environment variable

This adds a patch (submitted upstream in
PyO3/setuptools-rust#364), to read the profile
to pass to cargo from an environment variable.

This also updates the Python include files to set the environment
variable based on values from rust-values.mk.
