powerpc64: Add the clone3 wrapper
It follows the internal signature:
extern int clone3 (struct clone_args *__cl_args, size_t __size,
int (*__func) (void *__arg), void *__arg);
The powerpc64 ABI requires an initial stackframe so the child can
store/restore the TOC. It is create prior calling clone3 by
adjusting the stack size (since kernel will compute the stack as
stack plus size).
Checked on powerpc64-linux-gnu (power8, kernel 6.0) and
powerpc64le-linux-gnu (power9, kernel 4.18).
