Remove the dependency on `_Concurrency`
[OSLog] Remove the dependency on `_Concurrency`

_Concurrency is not used in the module, and having it as a dependency causes a ninja error when trying to build stdlib without `-D SWIFT_ENABLE_EXPERIMENTAL_CONCURRENCY=YES`:

```
ninja: error: 'stdlib/private/OSLog/swift_Concurrency-swiftmodule-macosx-arm64', needed by 'stdlib/private/OSLog/OSX/arm64/OSLogTestHelper.o', missing and no known rule to make it
```
