netfilter: clean up dependencies of kernel modules

Browse source 
The nf_reject_ipv4 and nf_reject_ipv6 modules are moved into separate
packages, as they are a common dependency of ip(6)tables and nftables. This
avoids a dependency of nftables on kmod-nf-ipt(6). Also, fewer iptables
modules depend on nf-conntrack(6) now.
