autotools: fix configure with python >= 3.8
Would fail like this with python >= 3.8:
configure: checking for libraries required to embed python
configure: error: Python libs not found. Windows requires Python modules to be explicitly linked to libpython.
Reason being that we must pass --embed now to python3-config to get the -lpython3.8 linker argument.

Also see commit 22f28155d86e27c4134de4ed2861264003fcfd23 for Meson.
