k3s: Add missing IP Virtual Server (ip_vs) feature to the kernel config

K3s (and Kubernetes) supports load balancing via IPVS, and by default reports
errors when IPVS kernel modules cannot be loaded.

This patch adds the missing reported kernel modules to the k3s recipe:

    * ip-vs
    * ip-vs-rr
    * ip-vs-wrr
    * ip-vs-sh

The modules are configured by including the ip_vs kernel feature.
