4.3BSD Net2 doesn't include the swapper in the load average calculation. I
also think we should exclude kernel threads given that the scheduler no
longer alters their priority. I think the test against PZERO in uvm_meter()
is intended to weed out LWPs that are sleeping interruptably. If so, that
one was broken before NetBSD came into being :-).

	if (l->l_priority > PZERO || l->l_slptime > 1)

With both of these fixed I now get reasonable numbers for load average..
