Add nftables to extended image
I would like to suggest adding the nftables package to the extended image (i.e. to profile_extended in scripts/mkimg.standard.sh). My rationale is
- extended is billed as being "Most common used packages included. Suitable for routers and servers."
- I think for a new installation router the right way to do a firewall is just to use straight nftables (i.e. manually edit /etc/nftables.nft); for comparison, OpenWrt's current stable version defaults to nftables
- if an installation is using nftables, it's critical and is needed for even minimal operation; I've been building a custom image just to get nftables included
