Workaround intermittent bugs with HEAD requests by disabling keepalive in HTTPClient.

I think this is a bug in Youtube's web server (sending chunked encoding of an empty body with a HEAD response, leaving the connection out of sync when it doesn't attempt to read a body) but the HTTP_Request2 library may need to be adjusted to watch out for that.
