global: use ktime boottime instead of jiffies

Since this is a network protocol, expirations need to be accounted for,
even across system suspend. On real systems, this isn't a problem, since
we're clearing all keys before suspend. But on Android, where we don't
do that, this is something of a problem. So, we switch to using boottime
instead of jiffies.
