CUDA aarch64 12.6 and 12.8 builds fix triton constraints (pytorch#165022)

CUDA aarch64 12.6 and 12.8 builds fix triton constraints (pytorch#165013)

Since we have introduced CUDA aarch64 builds for all cuda versions we need to remove this constraint.
This was missed by pytorch#162364

Proper constraint on triton should be:
```
Requires-Dist: triton==3.5.0; platform_system == "Linux"
```

not:
```
Requires-Dist: triton==3.5.0; platform_system == "Linux" and platform_machine == "x86_64"
```
