Add support for the clone3 system call to the SPARC architectures. The implementation follows the pattern of the original clone syscall. However, instead of explicitly calling kernel_clone, the clone3 handler calls the generic sys_clone3 handler in kernel/fork. In case no stack is provided, the parents stack is reused. The return value convention for clone3 follows the regular kernel return value convention (in contrast to the original clone/fork on SPARC).
