Avoid double slashes in URLs given to libdownload.

If a Server specified in pacman.conf had a trailing slash, libalpm ended up
building URLs with double slashes, and this broke libdownload with errors
like the following one :

error: failed retrieving file 'redland-1.0.8-1-i686.pkg.tar.gz'
from 192.168.0.90 : Command okay

So the public function alpm_db_set_server will make sure to remove the
trailing slash of servers.  For the private function
_alpm_download_single_file, I only added a comment.
