    Fix heron-downloader cannot load the jar package correctly (#3709)
    
    1. Install heron in the linux system to the /usr/lib/heron directory
    2. Create symbolic links of several executable files in heron/bin to the /usr/bin directory
    3. Try to call the heron* program separately, and the heron-downloader program fails to load the jar package correctly, and other programs are normal
