I added some steps for testing to D6036. You should be able to start with some testing partly decoupled from the actual process, a separate test buildbot worker is probably a good idea.

Your GPU doesn't meet the requirements for 2.80 and newer. For an AMD GPU at least GCN 1st is required, your card is TeraScale 2 ( https://en.wikipedia.org/wiki/List_of_AMD_graphics_processing_units#IGP_(HD_6000)_2 ). Unfortunately this means Blender 2.80 will not run properly on your hardware.

Well, setting up all that polling and messaging between slave_pack.py and the signing machine is what then needs to be set up and tested. With the buildbot we have already something that is tested and working with certainty, without having to write custom code that can fail.
