Bundle folder not available in DaemonContext

1. The DaemonContext recipe doesn't do anything. The list of fds it examines is empty.

2. The bundle folder goes away. I'm guessing this is because DaemonContext (and other daemonizers), fork and the initial process exits. This is why I can't find a cacert.pem. Is there a way to keep the folder around until the child exits?

Start with the DaemonContext recipe and the supplied frozen Python reproducer, especially files_preserve and the sys._MEIPASS existence checks. Trace bundle cleanup across the daemon fork and initial-process exit, then verify that the bundle remains available until the child exits.
