The `-a` from exec sets the `$0` from the process. So `exec -a "$0"`
would set the name of the new process to `nvidia-offload` (the name of
the script), however this is causing issues with a few programs that try
to interpret `$0` in a special way. For example, see `wine`:
```
$ nvidia-offload /nix/store/zhv91s26gsrl1w8yn9800xd03a31r3wj-wine-osu-7.0/bin/wine .osu/drive_c/osu/osu\!.exe
/nix/store/zhv91s26gsrl1w8yn9800xd03a31r3wj-wine-osu-7.0/bin/nvidia-offload: could not open
```
What I think `wine` is doing here is trying to re-exec `wine` again, but
to do so it tries to figure out the original call of wine by readind `$0`,
and will fail in this case because the `$0` was changed because of the
`nvidia-offload` script using `-a` flag, as explained above.
Instead, let's simplify this. There is no good reason to rename the `$0`
from the script anyway (it just sets a few environment variables), so let's
just remove it. We may lose the ability to know if the command is being
offloaded, but I think having more commands to work is a good trade-off.
Two reasons for this change:
- `intel` drivers are not updated from quite a long time (since ~2019),
and `modesetting` is the preferred one for Intel iGPUs.
- Technically you may want to disable NVIDIA GPUs on laptops with AMD
processors too.
We don't want to pin `modesetting` here because it is already the default
since PR: https://github.com/NixOS/nixpkgs/pull/111551.
This is already used in XPS 15-9560, but instead of defining it in XPS
15-9560 let's create a separate profile and expose it for those who want
to disable their NVIDIA GPU.
