In nftables we have the 'meta' extension that allows to match all
skbuff fields (among other things):

http://1984.lsi.us.es/git/nf-next/tree/net/netfilter/nft_meta.c?h=nf_tables8

I think it's the way to go so we stop adding small matches for each
skbuff field.

I don't mind the name if it's xt_skbuff or xt_meta.
