    download.pl: properly cleanup intermediate .hash file
    
    It seems like after a build the /dl dir seems to now contain a .hash
    file for each source file due to inproper cleanup so fix it by removing
    those intermediate files before leaving the download action.
    
    Fixes: 4e19cbc55335 ("download: handle possibly invalid local tarballs")
