python3: refactor python-config patch

Drop legacy python-config.patch

distutils is deprecated in Python 3.10 and will be removed in Python
3.12 (~October 2023).

Rather than wholesale import the distutils.sysconfig module, refactor
to replicate legacy distutils usage that we need.

This merges changes to get_python_inc from 12-distutils-prefix-is-inside-staging-area.patch

+Subject: [PATCH] python-config.in: implement legacy disutils behavior
+
+The sysconfig behavior does not provide the correct paths for our usage,
+but rather than continue to use the deprecated distutils.sysconfig
+behavior, refactor the code paths we need to use supported standard
+library functionality.

-Subject: [PATCH] python-config: Revert to using distutils.sysconfig
-
-The newer sysconfig module shares some code with distutils.sysconfig, but the same modifications as in
-
-12-distutils-prefix-is-inside-staging-area.patch makes distutils.sysconfig
-
-affect the native runtime as well as cross building. Use the old, patched
-implementation which returns paths in the staging directory and for the target,
-as appropriate.
