Handle nvidia-smi mismatch errors for archdetect.

[terjekv]

I ran into this as one of our build nodes had the driver mismatch:

$ nvidia-smi
Failed to initialize NVML: Driver/library version mismatch
NVML library version: 580.95

Sadly, this resulted in eessi_archdetect.sh setting EESSI_ACCEL_SUBDIR to an empty value, which again caused building CUDA software with EESSI-extend to fail with:

Note, this will make archdetect fail if nvidia-smi has a driver/library mismatch. This will have consequences for loading the EESSI module as it will now fail if there's a driver/library mismatch, even if the user loading the EESSI module has no intention of using the GPUs.

This may not be ideal.

Looks good overall. Minor suggestion on improving the information for a user.

Thanks for this PR @terjekv !

We discussed this at a support meeting and suggest the following:

• print the unaltered error message (e.g., just cat $nvidia_smi_out)
• print a hint how this could be fixed (you mentioned that you fixed this)

Does this sound ok?
