Remove ProtocolFactory use from appcache_url_request_job_unittest.

The test now uses its own URLRequestJobFactory instead.
This is being done to remove use of a deprecated API in net/

Also remove most friend classes outside net/ from
URLRequest::Deprecated, as none of them are needed any more,
except for AppCacheInterceptor.
