[request] Hide DE/VM if none found

[koutsie]

This has so far been the best fetch-a-like script I've found to add to my list of tools for esoteric linux handhelds but... maybe the DE/VM should show "none" if none are detected?
As I type this I could've made this a PR but I guess its wroth the discussion?

Thanks a lot, I really appreciate that you loved the script~!
As for the issue, one could easily make a custom config... So I'll just add the "none" soon!

Thanks for reporting the issue.
