PiBox

This should change so that each line has an identifier, as in:

VERSION: PiBox 2.0
HW: rpi2
BUILD: Fri Aug  4 20:58:17 UTC 2023
MODEL: Raspberry Pi 3 Model B Rev 1.2

This way we can avoid changes by line number.

I'm not sure what else uses this. The following command from just above all my sandboxes didn't find it referenced anywhere outside of the pibox build itself.

find pi* ironman appmgr launcher lcdshow libpibox metabuild musicfe pmsui pnc videofe -type f -exec grep -l "pibox-version" {} \;

So for now just make sure the dev system build skeleton handles these changes.

$ cdx
$ find * -type f -exec grep -l "pibox-version" {} \;
configs/buildroot.mk
src/buildroot/skeleton/etc/init.d/firstboot

It should be noted that this change isn't really necessary unless we change the config.txt too, since RPi3 optimizations exist there that prevent an RPi3 SD from being moved to an RPi2.

If you remove those optimizations then the SD will boot.

Changes tested on hardware (both with and without RPi3 optimizations) and they are working.
Changes committed and pushed.

Closing issue.
