Opt out -Zrustdoc-scrape-examples on docs.rs

I'd like a chance to audit all the code that rustdoc is inserting into
the docs. Currently I am skeptical that showing indoc's internal usages
of APIs is a net benefit to the public documentation. I am also
skeptical that quite so many examples are needed, and that they should
be featured so prominently in comparison to handwritten docs. Lastly I
wish there were a way to turn this behavior off on a more granular
basis.
