Include golang in dietpi-software

The repo version of Golang is way behind the official release site so I think this is a prime package for inclusion in the fabulous dietpi-software system.

Planned for next release. We have the Golang Go install code already as part of the OpenBazaar install, but will move then into a separate install option.

Here the install code (warning, the script is huge so takes a time to load in browser :slight_smile:):

Version will be switched from hardcoded to latest, which until now always worked fine with OpenBazaar as well, i.e. it never failed when I tested it with recent Go and raised the hardcoded string accordingly.
