  [Clang] Add env var for nvptx-arch/amdgpu-arch timeout (#102521)

When working on very busy systems, check-offload frequently fails many
tests with this diagnostic:

```
clang: error: cannot determine amdgcn architecture: /tmp/llvm/build/bin/amdgpu-arch: Child timed out: ; consider passing it via '-march'
```

This patch accepts the environment variable
`CLANG_TOOLCHAIN_PROGRAM_TIMEOUT` to set the timeout. It also increases
the timeout from 10 to 60 seconds.
