Remove reference to google search service that was discontinued in 2011

Summary

While reviewing the translated version of this article (pt_BR) I saw that the Google service for specific BSD searches referenced in this article was disabled in 2011.

There is more details about this service being discontinued at:

Google discontinues BSD Search (google.com/bsd)

Due that I believe it would be correct to remove the phrase from the article that references it.
