    scripts/download.pl: pass aria2 config in ENV only
    
    The aria2c command tries to load config from
    ${XDG_CONFIG_HOME:-${HOME}/.config}/aria2/aria2.conf by default,
    which may result unexpected behavior.
    
    As a replacement, people can use environment variable ARIA2C_OPTIONS
    to custom arguments passed to aria2c like curl and wget below.
    Including --conf-path=/path/to/config.conf in ARIA2C_OPTIONS can
    also set a custom config file path easily if needed.
