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
