dload: avoid showing progress bars on some redirects
RFC 2616 doesn't forbid a 301 or 302 repsonse from having a body, and servers exist in the wild that show this behavior. In order to prevent pacman from showing a progress bar when we aren't actually downloading a package (and merely following one of these pain in the butt redirects), capture the server response code in the response header, rather than waiting to peel it off the handle after the download has finished.
