Partially extracted from #7547 Updates protobuf to the most recent in the 1.3.x series, and updates golang.org/x/sys to a7d97aace0b0 because of https://github.com/shirou/gopsutil/issues/853 prevents updating to a more recent version. This breaking change in x/sys also prevents us from getting a newer version of x/net. In the future, if gopsutil is not patched, we may want to run a fork version of gopsutil so that we can update both x/net and x/sys.
