Correctly accumulate gs upload URLs

https://crrev.com/c/6796221 added a gsutil_urls output property that
provides the URLs of uploads to Google storage that were performed by
the build. It attempts to accumulate the URLs by updating a dictionary
on the result object's properties, but the properties on a step's
results object is empty when created, so it was just overriding the
property each time with a single element dict. This change keeps the
dict on the API object and updates it when an upload is performed so
that the final value includes all of the URLs produced by the build.
