lakitu_defconfig: Enable nftables flow offload and flowtable support

Enable the following nftables options to support the new kube-proxy
implementation based on nftables with kernel bypass acceleration
using the netfilter flowtable infrastructure:

- CONFIG_NFT_FLOW_OFFLOAD: Enables offloading of nftables rules to
  hardware.
- CONFIG_NF_FLOW_TABLE_INET: Enables the flowtable infrastructure for IPv4
  and IPv6.
- CONFIG_NF_FLOW_TABLE_PROCFS: Enables the procfs interface for the
  flowtable.

BUG=b/388464961
TEST=presubmit
RELEASE_NOTE=Added support for nftables flow offload and the flowtable
infrastructure.
