Remove byte_range param on aria2c downloader

Turns out, even if you manually set the Range header AND the server has full support, it does not work. It will act like it works, but it seems internally aria2c gets confused on what bytes it requested, what it returned, and it will either just download the full file, or the range requested (but still complain, and freeze!).

Yikes.
