nft: Eliminate table list from cacheHEADmaster

The full list of tables in kernel is not relevant, only those used by
iptables-nft and for those, knowing if they exist or not is sufficient.
For holding that information, the already existing 'table' array in
nft_cache suits well.

Consequently, nft_table_find() merely checks if the new 'exists' boolean
is true or not and nft_for_each_table() iterates over the builtin_table
array in nft_handle, additionally checking the boolean in cache for
whether to skip the entry or not.
