Make cuda version check dynamic

[casparvl]

Fixes #189

First step to fixing #201

Unblocks #200 , which blocks EESSI/software-layer#1462 which blocks EESSI/software-layer#1453 ...

This PR can be modified by modifying the create_lmodsitepackage.py with something like:

                if not cudaVersion or cudaVersion == "" then
                    -- Hardcode for local testing
                    -- local eessi_prefix = os.getenv("EESSI_PREFIX")
                    local eessi_prefix = pathJoin('/home', 'casparl', 'EESSI', 'software-layer-scripts')
                    local script = pathJoin(eessi_prefix, 'scripts', 'gpu_support', 'nvidia', 'get_cuda_driver_version.sh')

This now correctly sets EESSI_CUDA_DRIVER_VERSION=13.1 on my RTX Pro 6000.

Forcing it to e.g. 12.0 and loading something that needs CUDA 12.9.1 prints a nice error:

Your driver CUDA version is 12.5  but the module you want to load requires CUDA 12.9.1.

With 12.9 it works fine, as expected, as it doesn't check the patch version.

Just to test failures of the script, I modified the script and hardcoded an empty string for the driver version. Then I get the following, as expected:

Lmod Warning:  Environment variable EESSI_CUDA_DRIVER_VERSION not found. Cannot ensure that driver version is new enough for CUDA toolkit version: '12.9.1'. This module
will still be loaded, but may not function as expected. Export EESSI_CUDA_DRIVER_VERSION_SUPPRESS_WARNING=1 

Setting that env var allowed me to load the module.
