Align Tornado default service with traced span service

Set _default_service to the same value Tornado spans actually use by default, otherwise the new _dd.svc.src tagging path never triggers for Tornado. application.tracer_config initializes request/template tracing with default_service = schematize_service_name(config._get_service("tornado-web")), but this change hard-codes _default_service as schematize_service_name("tornado"); as a result, default Tornado spans (tornado.request and tornado.template) won't satisfy the equality check used by maybe_set_service_source_tag, so the feature added in this commit is effectively disabled for Tornado.
