Fix swift_stdlib_tool remote-exec failure (#1036)
Fix swift_stdlib_tool remote-exec failure (#1036)

The `destination_path` might not exist on the worker. It seems that `swift_stdlib_tool` currently works because bazel implicitly creates the directory locally when `declare_directory()` is used. To fix this we need to ensure the output directory is created in `swift_stdlib_tool`.
