ewaol-distro/linux,k3s: Drop upstreamed IPVS kernel configs and modules install

The linux kernel config necessary for IP Virtual Server (IPVS) support, as used
by K3s, has been included in the upstream meta-virtualization kubernetes kernel
config fragment, and the kernel module dependencies are now installed as part of
the upstream k3s recipe. Therefore, they are no longer required as part of
meta-ewaol and are removed.
