python3: rename patches to the new convention

Note that we don't use completely sequential numbers, because patches
below 100 are used to address cross-compilation issues in Python 3,
while patches above 100 are used to make more Python 3 modules
configurable.

+distutils: fix build_ext check to find whether we're building Python or not
+
+The build_ext logic uses
+sys.executable.startswith(os.path.join(sys.exec_prefix, "bin")) to
+determine whether we're building a third-party Python extension, or a
+built-in Python extension. However, this check is wrong in
+cross-compilation mode, and instead, the sysconfig.python_build
+variable should be used.
