`dotnet` CLI does not work under gVisor

### Describe the bug

I am trying to use `mcr.microsoft.com/dotnet/sdk` under a gVisor environment on arm64 (Apple Silicon). Most commands fail with the following error:
```
Fatal error. AdvSimd processor support required.
Aborted
```

### To Reproduce

You will need gVisor set up as an additional container runtime.

This command succeeds:
```
$ docker run -it --runtime runsc mcr.microsoft.com/dotnet/sdk:8.0.401-bookworm-slim dotnet

Usage: dotnet [options]
Usage: dotnet [path-to-application]

Options:
-h|--help Display help.
--info Display .NET information.
--list-sdks Display the installed SDKs.
--list-runtimes Display the installed runtimes.

path-to-application:
The path to an application .dll file to execute.
```

This command fails:
```
$ docker run -it --runtime runsc mcr.microsoft.com/dotnet/sdk:8.0.401-bookworm-slim dotnet --version
Fatal error. AdvSimd processor support required.
```

`dotnet new|build|pack` also fail with the same error.

### Exceptions (if any)
The same commands (`dotnet --version` and others) work for the following images:
- mcr.microsoft.com/dotnet/sdk:7.0-bookworm-slim
- mcr.microsoft.com/dotnet/sdk:6.0-bookworm-slim

### Further technical details
I am targeting the arm64 arch (running under Apple Silicon). I have not tested this under any other arch.

`dotnet --info` fails under `sdk:8`, but `sdk:7` returns the following:
```
$ docker run -it --runtime runsc mcr.microsoft.com/dotnet/sdk:7.0-bookworm-slim dotnet --info
