More KoboUSBMS related tweaks & cleanups (#6590)

* Be even more defensive around KoboUSBMS handling in the startup script

And add some more logging. To the log before a session, to the syslog
after, because we can't be sure onboard is viable.

* Display a short version string straight in the Version label

* Move system statistics inside the Help menu

* Move Version inside Help


* Bump base
