Fix a ChromeFrame crash which occurs while uploading UMA data. We use Chrome's http stack in
ChromeFrame to upload this data. The crash occurs in the HttpAuthHandlerNegotiate code while
attempting to perform a DNS resolution with a null HostResolver pointer. 

Fix is to use the  net::HttpAuthHandlerRegistryFactory::Create function to create the AuthHandler factory as this function takes in
the host resolver as an argument.
