kprobes: switch to kernel_clone()

Browse Source 
The old _do_fork() helper is removed in favor of the new kernel_clone() helper.
The latter adheres to naming conventions for kernel internal syscall helpers.

* NOTE: This example is works on x86 and powerpc.

* You will see the trace data in /var/log/messages and on the console
