netfilter: remove messages print and boot/module load time

Several reasons for this: * Several modules maintain internal version numbers, that they print at boot/module load time, that are not exposed to userspace, as a primitive mechanism to make revision number control from the earlier days of Netfilter. * IPset shows the protocol version at boot/module load time, instead display this via module description, as Jozsef suggested. * Remove copyright notice at boot/module load time in two spots, the Netfilter codebase is a collective development effort, if we would have to display copyrights for each contributor at boot/module load time for each extensions we have, we would probably fill up logs with lots of useless information - from a technical standpoint. So let's be consistent and remove them all. Acked-by: Florian Westphal <fw@strlen.de> Acked-by: Jozsef Kadlecsik <kadlec@blackhole.kfki.hu> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
