[youtube] Fix ytsearch* when cookies are provided

Closes #11924

The API with `page` is no longer used in browsers, and YouTube always
returns {'reload': 'now'} when cookies are provided.

See http://youtube.github.io/spfjs/documentation/start/ for how SPF
works. Basically appending static link with a `spf` parameter yields the
corresponding dynamic link.
