Fix empty IPV4 gateway error

If an IPV4 gateway is empty use "0.0.0.0".

The RedfishServiceValidator throws the following error on
a Witherspoon system:
"IPv4Addresses[0].Gateway: String '' does not match pattern
''^(?:[0-9]{1,3}\\.){3}[0-9]{1,3}$''"

Tested: Ran RedfishServiceValidator and no longer observe the
        error. IPV4 addresses with gateways are untouched.
