s/sentinel/declared ctl array

Because the you're suggesting we want to remove the sentinel but we
want to help the patch reviewer know that a sentil is required per
declared ctl array.

You can also mention here briefly that this helps ensure that future moves of
sysctl arrays out from kernel/sysctl.c to their own subsystem won't
penalize in enlarging the kernel build size or run time memory consumption.

Thanks for spinning this up again!
