Enable close-on-exec on socket #651

  1. Enable close-on-exec flag when opening the tun device node. 

    When the close-on-exec flag is set, the file descriptor is automatically
closed upon a successful exec. This keeps a child process--such as one
started using system()--from inheriting the file descriptor.
