netfilter: xtables: allow xtables-nft only builds
Add hidden IP(6)_NF_IPTABLES_LEGACY symbol.
When any of the "old" builtin tables are enabled the "old" iptables
interface will be supported.
To disable the old set/getsockopt interface the existing options
for the builtin tables need to be turned off:
CONFIG_IP_NF_IPTABLES=m
CONFIG_IP_NF_FILTER is not set
CONFIG_IP_NF_NAT is not set
CONFIG_IP_NF_MANGLE is not set
CONFIG_IP_NF_RAW is not set
CONFIG_IP_NF_SECURITY is not set
Same for CONFIG_IP6_NF_ variants.
This allows to build a kernel that only supports ip(6)tables-nft
(iptables-over-nftables api).
In the future the _LEGACY symbol will become visible and the select
statements will be turned into 'depends on', but for now be on safe side
so "make oldconfig" won't break things.
