Sets the file path to use as the stderr for spawned processes.
If @path is %NULL then any previously given path is unset.
The file will be created or truncated when the process is spawned, as would be the case if using '2>' at the shell.
If you want to send both stdout and stderr to the same file then use %G_SUBPROCESS_FLAGS_STDERR_MERGE.
You may not set a stderr file path if a stderr fd is already set or if the launcher flags contain any flags directing stderr elsewhere.
This feature is only available on UNIX.
