tests: Enable VFIO integration tests

Re-enable the VFIO integration now the machine is back online.

The image has been updated to rely on Ubuntu 22.04 (Jammy) and it's
smaller given only the NVIDIA drivers along with the nvidia-smi tool are
installed.

The test to verify the GPU is functional has been simplified given it
only relies on nvidia-smi to validate it has been able to find the Tesla
T4 card, meaning the associated driver was loaded correctly.
