iptables-compat: Keep xtables-config and xtables-events out from tree
These binaries are part of the compat layer, however they provide more features than actually available in the existing native iptables binaries. So let's keep them out from the tree before the 1.6.0 release as we only want to provide compatibility utils at this stage. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
