Make tests/gpu-container adapt to available HW

[simondeziel]

This was tested on rockman using:

PURGE_LXD=1 ./bin/local-run tests/gpu-container latest/edge

rockman has the particularity of having 3 GPUs, one onboard Matrox and 2x NVIDIA L40.

@escabo with this, you should be able to run the tests/gpu-container unaltered on your own hardware, at least that's the theory and if that still requires modification to pass, I'd like to hear about it, thanks!

I ran sudo bin/local-run tests/gpu-container latest/candidate and it failed.

The machine has secure boot and when I install the (Nvidia) driver manually, I have to go through creating a pw that I am asked on the next boot to register the new keys. Can/does the script work around this?

Also, the script installs 525 but if I run sudo ubuntu-drivers devices, the recommended one is 535. Could this be part of the script to avoid having to update the required version every so often?

If I install the driver manually, the test works! I had to install jq on the host.
