configure.ac: Add a --without-python option.
Being able to be explicit about Python support (in addition to the default of auto-detecting it) and acting upon the result, specifying it as an option gains us more control about both dependencies and the resulting build. Furthermore, relying purely on auto-detection can lead to problems for source-based distros. E. g. systemd being built before *both* 32-bit & 64-bit ABIs are installed will lead to build failures as systemd's build system will pick up either 32-/64-bit Python, conclude both are available and fail if that's not the case.
