make kerl use 'curl -o $filename ...' when downloading files

Instead of piping output to a file, use curl's '-o' option.

This change is intended to work around a problem I encountered where I had `-w "\n"` in my `~/.curlrc` file, which caused these commands to produce output that failed the md5 checks.
