[issue38353] Cleanup the path configuration implementation code (getpath.c)

[STINNER Victor]

STINNER Victor <vstinner at python.org> added the comment:

On my Fedora 30, GCC doesn't complain on "typedef struct pyruntimestate _PyRuntimeState;". But clang on macOS emits a warning, saying that it's C11-only feature. So I modified the internal header files to use "struct pyruntimestate" instead, to avoid any compilation issue.
