    app-admin/collectd: bump, fixes CVE-2017-16820 & #628540
    
    Ebuild changes:
    ===============
    - To address bug 628540, we no longer run collectd in
      daemon mode, instead we will run collectd everywhere
      in foreground and let the init system handle the PID
      file.
    
    - /run/collectd/ (default location for collectd's UNIX socket)
      is now maintained using tmpfiles service.
