nftables is the modern packet filtering solution on Linux. The nftables userspace can be installed alongside iptables, but in general, only one can be enabled at once. This commit adds the userspace but does not do anything with the present iptables-based firewall configuration. At present, there are no plans to introduce nftables into safemode, so add it to the runmode packagegroup, not base. Signed-off-by: Rich Tollerton <[email protected]>
firewalld is the best-maintained high-level firewall administration tool on Linux. We ultimately wish to replace our present direct use of iptables (via initscript) with firewalld; but at present the existing configuration is unchanged. Signed-off-by: Rich Tollerton <[email protected]>

Summary of Changes
Add nftables (modern Linux packet filtering support) to runmode; disabled by default.
Add firewalld (modern Linux high-level firewall administration tool) packages to SNAC. (nftables is in runmode, not SNAC, for symmetry with the kernel configuration, which will include the NFT modules in runmode too.)
The existing iptables initscript is unchanged. This is tracked by Azure DevOps workitem AB#2823118.
Note: this is a continuation of #725, rebased to
nilrt/master/next.Testing
Built nilrt-base-system-image and confirmed it runs on a VM. nft runs; iptables still runs. firewall-cmd is not yet tested.
This change will grow the uncompressed BSI by approximately 9.5MB; see #725 for details.
