Remove usage of URLRequestFailedJobs::GetMockHttpUrl in content/

This CL removes usage of URLRequestFailedJobs::GetMockHttpUrl in
content. This function was used to simulate a connection error in some
navigation browser tests, but it is not supported by the network
service. Instead we use the "/close-socket" handler of the
EmbeddedTestServer which will result in a connection closure when the
URL is requested.
