Backport Go 1.20 from Poky Mickledore

Issue

Kanto Container Management did a breaking change by bumping their Moby dependency to a newer version. Now to build Kanto Container Management it is required go 1.19 or newer to be available and poky kirkstone only provides Go 1.17+. Newer Poky releases (after kirkstone) are not LTS releases so we do not want necessary to move to a newer yocto version.

Solution

This PR takes the recipes from Poky Mickledore directly and backports them to a new compatibility layer meta-leda-backports and updates the GOVERSION variable to GOVERSION ?= "1.20%". With this compatibility layer you can now build Kanto Container Management.

The container-management recipe is again set to use AUTOREV (compile the latest development version of Kanto Container Management)

Licenses

Recipes-devtools from Poky Mickledore are licensed under a MIT license. That's why the License notice is included and re-distribution of those recipe sources is otherwise okay.
