bson.json_util does not properly serialize the UUID binary sub type

      The UUID sub type should be encoded as 

      { "$binary": "<bindata>", "$type": "<t>" }

      according to the documentation:
      https://docs.mongodb.com/manual/reference/mongodb-extended-json/#binary

      This is also what the server does: https://github.com/mongodb/mongo/blob/master/src/mongo/dbtests/jsontests.cpp#L1396

      Example of the current behavior

      >>> import bson
>>> from bson import json_util
>>> from bson.binary import UUID
>>> json_util.dumps({'uuid': UUID('f47ac10b-58cc-4372-a567-0e02b2c3d479')})
'{"uuid": {"$uuid": "f47ac10b58cc4372a5670e02b2c3d479"}}'
