sysctl: remove broken netfilter binary sysctls

No one has bothered to set strategy routine for the the netfilter sysctls that
return jiffies to be sysctl_jiffies.

So it appears the sys_sysctl path is unused and untested, so this patch
removes the binary sysctl numbers.

Which fixes the netfilter oops in 2.6.23-rc2-mm2 for me.
