sparc: Add architecture support for clone3
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).
