    scripts/dowload.pl: use glob to expand target dir
    
    If CONFIG_DOWNLOAD_FOLDER is set to for example "~/dl", the download
    script fails to create the .hash and .dl files with the following
    errors:
     Cannot create file ~/dl/dropbear-2017.75.tar.bz2.dl: No such file or directory
     sh: 1: cannot create ~/dl/dropbear-2017.75.tar.bz2.hash: Directory nonexistent
    
    If the tarball already exists in the ~/dl dir, it's properly found and
    used, so this issue only affects the download.pl script.
     This patch calls glob() on the target dir parameter, which will expand `~`.
