    build: use python3 exclusively

    Python 2 is deprecated and is going to be removed from Linux
    distributions in the short term [1,2]. Thus, (parts of) the build
    process will fail on current systems like e.g. Debian unstable.

    The /bin/python binary is not going to exist anymore. The canonical
    name for the Python 3 binary is, you guess it, /bin/python3. So, let's
    just use this during our build process and go future proof.

    Fixes #1158.
