[PATCH 2/2] Don't drop journalctl content if failure action is "shell"

If failure action is set to "shell", user will need more debug info available in kdump kernel. Especially when serial console is not available, manually retrieve the log from journalctl is very useful for debugging kdump issue. Else, we can still drop journalctl content to save memory assuming nothing will use it.
