    busybox: Save shell history into /tmp
    
    Enable the busybox feature to save shell command history.
    (.apk size increase 0.5 kB)
    
    To prevent flash wear,
    * save history only at the exit from a shell session, and
    * set /tmp as the default location for the history file. The history
      is kept on ramdisk until a reboot, when the history is then lost.
    
    If the user wants to save history onto flash, he can change the location
    definition in /etc/profile.d/busybox-history-file.sh
