Both legacy iptables and nftables require nf-log modules for rule logging,
so move them into a separate package both firewall implementations can
depend on.

It's related to the upstream kernel commit adf82accc5f5 ("netfilter:
x_tables: merge ip and ipv6 masquerade modules").
Signed-off-by: Rafał Miłecki <rafal@milecki.pl>
In mainline kernel commit 02c7b25e5f5 ("netfilter: nf_tables: build-in
filter chain type") all chain filters were merged into one file and into
one kernel module to save some memory. The code protected by these
configuration options CONFIG_NF_TABLES_BRIDGE, CONFIG_NF_TABLES_IPV4,
CONFIG_NF_TABLES_ARP, CONFIG_NF_TABLES_IPV6, CONFIG_NF_TABLES_NETDEV and
CONFIG_NF_TABLES_INET was merged into the nft_chain_filter.c file which
is now always compiled into the nf_tables.ko file.
This only happened in kernel 4.19 and OpenWrt has to select these as
modules in older kennel versions. Mark them as build-in in the kernel
4.19 specific kernel configuration file which will then not be
overwritten by the package specific settings which try to make them
modular again.

In kernel commit 0168e8b361 ("netfilter: nat: merge ipv4/ipv6 masquerade

to bool and the code will not be compiled as a own module any more, but
it will be integrated into nf_nat_ipv4.ko or nf_nat_ipv6.ko to save some
memory.
Activate these options as bool in the generic kernel 4.19 configuration
only, to always build them into the nf_nat_ipv*.ko modules. The kmod
file will still try to select them as module, but the generic
configuration will not be overwritten.

The package kmod-ipt-debug builds the module xt_TRACE, which allows
users to use '-j TRACE' as target in the chain PREROUTING of the table
raw in iptables.
The kernel compilation flag NETFILTER_XT_TARGET_TRACE is also enabled so
that this feature which is implemented deep inside the linux IP stack
(for example in sk_buff) is compiled.
But a strace of iptables -t raw -I PREROUTING -p icmp -j TRACE reveals
that an attempt is made to read /usr/lib/iptables/libxt_TRACE.so, which
fails as this dynamic library is not present on the system.
I created the package iptables-mod-trace which takes care of that, and
target TRACE now works!
