DNS: Remove workaround for empty list array

This workaround is no longer needed with bmcweb.

curl  -k -H "Content-Type: application/json" -X PUT \
-d '{"data": [] }' \
https://${bmc}/xyz/openbmc_project/network/eth0/attr/Nameservers
{
  "data": null,
  "message": "200 OK",
  "status": "ok"

and actually casues an error now do to
https://github.com/openbmc/phosphor-networkd/commit/5fb6c33a49ee2b9718cc9ce0f921d3b6cf38a463

curl  -k -H "Content-Type: application/json" -X PUT \
-d '{"data": [""] }' \
https://${bmc}/xyz/openbmc_project/network/eth0/attr/Nameservers
  "data": {
    "description": "xyz.openbmc_project.Common.Error.InvalidArgument"
  },
  "message": "Invalid argument was given.",

See https://github.com/openbmc/openbmc/issues/3240

Tested: Built and loaded on a Witherspoon. Added, removed,
        and edited DNS servers.
