Use extension for Lima X.Org serverflags

* Remove create_desktop_package.sh for rk3318 board from
   config/optional, clearing the whole directory tree
 * Add an extension to implement serverflags workaround
   for X.Org and Lima driver not being autodetected
 * Fix rk3318-box and rk322x family to use extension in place
   of 40-serverflags.conf bsp file
