[evolution-data-server/camel-socks-proxy] Use 'localhost' instead of NULL to resolve ports

    Use 'localhost' instead of NULL to resolve ports
    
    camel_getaddrinfo() does not take NULL hostnames, in contrast with
    getaddrinfo().  So for now we'll use localhost and try to do
    better in the future.
