[fd/external] Scope cookies

- ffmpeg: Calculate cookies from cookiejar and pass with `-cookies` arg instead of `-headers`
- aria2c, curl, wget: Write cookiejar to file and use external FD built-in cookiejar support
- httpie: Calculate cookies from cookiejar instead of `http_headers`
- axel: Calculate cookies from cookiejar and disable http redirection if cookies are passed
    - May break redirects, but axel simply don't have proper cookie support
