ci: Enable baremetal VFIO integration tests

Browse Source 
Relying on a NVIDIA Tesla T4 card present in the SGX machine, this patch
enables baremetal VFIO testing, validated by running several NVIDIA
tools in the guest. The guest image has been prepared to include all the
software needed to run these tests.
