[Buildroot] [git commit] daq: libdnet is optional not mandatory

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=fadd4a9f1c0b86a0c1a0bcbe70bed1b781a2af50
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

libdnet is an optional dependency, it is only needed if nfq or ipq
module are enabled.

So, if libdnet and libnetfilter_queue are available, enable nfq module
and add a dependency to both packages otherwise disable nfq module.

Moreover, always disable ipq module as libipq is deprecated, it isn't
enable in iptables. Even if it was enabled, libipq.h can't be included
as it makes a reference to linux/netfilter_ipv4/ip_queue.h which is not
available anymore
