ci: Capture artifacts in baremetal mode
In docker mode, artifacts handling just works. In baremetal mode, we need some way to get files off of the DUTs and on to the box with gitlab-runner. My current thought is to bring up nginx inside the gitlab-runner job with an upload location, and pass the address of that to the job on the DUT and use wget to upload a tar file containing them once the dEQP run is done.
