[NETFILTER]: Switch to using ctl_paths in nf_queue and conntrack modules

Browse Source 
This includes the most simple cases for netfilter.

The first part is tne queue modules for ipv4 and ipv6,
on which the net/ipv4/ and net/ipv6/ paths are reused
from the appropriate ipv4 and ipv6 code.

The conntrack module is also patched, but this hunk is
very small and simple.
