configure: some Python test cleanup/improvements.
In particular, when header check fails, Python option is disabled.
Also let's use pkg-config to search for the Python include directory.
The reason is that include/python{version} is not always
true. On my system in particular, python3.7 was in `include/python3.7m`.
