Fix an inefficiency in json-serializing a dynamic with sorted keys

Summary:
[Folly] Fix an inefficiency in json-serializing a `dynamic` with sorted keys.

The inefficiency is that, at each level of the `dynamic` which is map-typed, we effectively make a full copy of the `dynamic` object. This can be expensive.
