android_rvh_sched_fork() and android_rvh_sched_fork_init()
already let us register probes during fork(), but those are
invoked *before* the new task is added to the tasklist, which
can lead to some undesired races when a module is trying to
initialize vendor-specific task_struct fields.
Export the task_newtask tracepoint to register probes to run
during fork() but *after* the task has been inserted into the
tasklist.
