netfilter: move the sysctl nf_hooks_lwtunnel into the netfilter core

Browse source

Currently, the sysctl net.netfilter.nf_hooks_lwtunnel depends on the
nf_conntrack module, but the nf_conntrack module is not always loaded.
Therefore, accessing net.netfilter.nf_hooks_lwtunnel may have an error.

Move sysctl nf_hooks_lwtunnel into the netfilter core.
