add check for uuid-runtime package on OctoPi

[glenstewart]

My install was missing the uuidgen command, needed by the script. After it failed repeatedly trying to run uuidgen, I installed uuid-runtime and the new instance was created properly.

Please add a check for uuid-runtime package (uuidgen) on OctoPi

Thanks!!

It does attempt to install uuid-runtime. It is not clear why it fails, but it only fails with OctoPi.
