don't run runonce unless user is on a very old version of pi-apps

if the user is running GUI_FORMAT_VERSION unset or 1, then they have the old updater that was not part of the manage daemon. so spawning a new GUI will not be part of the manage daemon and will succeed.

if the user is on GUI_FORMAT_VERSION 2 then the likelyhood that they have the new manage daemon updater is high so we can not simply respawn the GUI since it would be a child process of the manage daemon (and would be killed after the 30 second timeout). So we are forced to detect this and kill the GUI process and yad window and tell the user to restart pi-apps themselves.
