Arturo Borrero 0071e184a5 netfilter: nf_tables: add support for inverted logic in nft_lookup 
Introduce a new configuration option for this expression, which allows users
to invert the logic of set lookups.

In _init() we will now return EINVAL if NFT_LOOKUP_F_INV is in anyway
related to a map lookup.

The code in the _eval() function has been untangled and updated to sopport the
XOR of options, as we should consider 4 cases:
 * lookup false, invert false -> NFT_BREAK
 * lookup false, invert true -> return w/o NFT_BREAK
 * lookup true, invert false -> return w/o NFT_BREAK
 * lookup true, invert true -> NFT_BREAK
