Subject: [PATCH] API: Set robots noindex,nofollow on HTML output

There's probably not much benefit in search engines indexing the API
auto-generated help or various random "format=jsonfm" outputs.

On Wikimedia wikis we already have a robots.txt entry denying indexing
of everything under /w/, which includes api.php.

Bug: T207818
Change-Id: I196d401eeb5fcf49844265df41ad3cce83ffdcdf
