Always generate a .toolchain file even if it is empty.

This removes a regression that was introduced in [1],
where a GN toolchain that only has empty group() targets
would not generate a .toolchain file anymore. This would
result a Ninja failure when the top-level build.ninja
file would try to load it. E.g.:

```
2.56s Error: failed to load build.ninja: open clang_x86/toolchain.ninja: no such file or directory
```

See [2] for complete example.
