timecounting: provide a naptime variable for userspace via kvm_read(3)

vmstat(8) uses kvm_read(3) to extract the naptime from the kernel.
Problem is, I deleted `naptime' from the global namespace when I moved
it into the timehands.  This patch restores it.  It gets updated from
tc_windup().  Only userspace should use it, and only when the kernel
is dead.

We need to tweak a variable in tc_setclock() to avoid shadowing the
(once again) global naptime.
