ProgressBar: Fix some rendering issues

- Do not hardcode terminal width of 100 chars, that breaks rendering on
  smaller terminal. It already uses current console width by default.
- Disable progress bar when downloading from msubprojects because it
  fetches multiple wraps in parallel.
- Scale unit when downloading e.g. MB/s.
- Do not display rate when it's not a download.
- Do not display time elapsed to simplify the rendering.
