I doubt this is really useful in general. SIGCHLD doesn't queue,
if the parent of init already has the pending SIGCHLD it won't see
CLD_REBOOTED anyway. Anyway, you do not need a special helper to
fill siginfo.

And personally I strongly dislike SA_CLDREBOOT. For what? Imho, this
is unnecessary complication. If we want SIGCHLD-on-reboot, just send
it unconditionally.
