Modify the default lighttpd configuration file to have one a starting conf

  * Changed the log path to /var/log and logs filenames
  * Disable IPv6
  * Do not setuid to a user that doesn't exist on the system
  * Disable pdf ranges fix for Adobe Reader since it uses regex and we
    don't always have pcre support
  * Change the network backend to writev since linux-sendfile fails on buildroot
