Disable zerocopy by default for now. It's causing some problems in pcap
consumers which fork after the shared pages have been setup. pflogd(8)
is an example. The problem is understood and there is a fix coming in
shortly.
Folks who want to continue using it can do so by setting
net.bpf.zerocopy_enable
to 1.
