encoding/jsonpb: fix encoding of empty google.protobuf.Value

Description of message Value states:

`Value` represents a dynamically typed value which can be either null, a
number, a string, a boolean, a recursive struct value, or a list of values. A
producer of value is expected to set one of that variants, absence of any
variant indicates an error.
