[PATCH 0/3] automation: add livepatch testing

[Roger Pau Monne <roger.pau@xxxxxxxxxx>]

Hello,

The following series attempts to introduce some basic livepatch testing
in the gitlab CI loop.  Such testing will be more similar to what
downstreams use, as the patch payload will be built using
livepatch-build-tools.

A sample gitlab run can be found at:

https://gitlab.com/xen-project/people/royger/xen/-/pipelines/1082636267

The series introduces a new build and test steps.

Thanks, Roger.
