xtables-restore: Minimize caching when flushing
Unless --noflush was given, xtables-restore merely needs the list of
tables to decide whether to delete it or not. Introduce nft_fake_cache()
function which populates table list, initializes chain lists (so
nft_chain_list_get() returns an empty list instead of NULL) and sets
'have_cache' to turn any later calls to nft_build_cache() into nops.
If --noflush was given, call nft_build_cache() just once instead of for
each table line in input.
