Try to help embedded systems a _little_ bit: stir in the system boot time
as early as possible. On systems with no cycle counter (or very very
predictable cycle counts early in boot) at least this will cause some
difference across boots.
Don't wait until the pool *fills* to rekey anything that was keyed with
insufficient entropy at boot: key it as soon as it makes any request after
we hit the minimum entropy threshold.
This too should help avoid predictable output at boot time.
Fix kern/46911: note that we rekeyed the cprng so we don't keep doing so.
