This patch split the nft_log module in AF-specific modules.
For NFPROTO_INET, it does nothing but dispatch to the AF-specific modules.
The main benefit of this patch is that we can now use nft_log from userspace
without being force to modprobe ipt_LOG, which was an annoying bug.
Some new symbols are added to Kconfig: NFT_LOG_IPV4, NFT_LOG_IPV6 and
NFT_LOG_INET.

v2: actually solve the nft_log issue regarding the need to load ipt_LOG.
