setStdinFilePath
Sets the file path to use as the stdin for spawned processes.
If @path is null then any previously given path is unset.
The file must exist or spawning the process will fail.
You may not set a stdin file path if a stdin fd is already set or if the launcher flags contain any flags directing stdin elsewhere.
This feature is only available on UNIX.
