startup probably isn't the right place for this.  It probably should just go in
chrome/browser/extensions.

Even if ChromeDriver weren't loading an extension, I think it's still reasonable
to show a warning to the user. So I don't really see this infobar as an
extensions-specific thing, what do you think?

I don't feel very strongly, so I'll let a ui or ui/startup owner decide. :)
