  - Remove the "nftables" explicit CI jobs

    The latest supported OS use the "iptables" compatible binary provided
    by tje "nftables" framework. The "iptables" commands are actually using
    the "nftables" backend. This patch removes the installation of the
    compatible binaries because this is now redundant.
