Mark Johnston e6de40fa79 Fix handling of rights on stdio streams.
- Limit rights on stdio before opening input files.  Otherwise, open()
  may return one of the standard descriptors and we end up limiting
  rights such that we cannot read from one of the input files.
- Use caph_limit_stdio(), which suppresses EBADF, to ensure that
  we don't emit an error if one of the stdio streams is closed.
- Don't bother further limiting rights on stdin when stdin isn't going
  to be used.  Doing so correctly requires checking for a number of
  edge cases, and it doesn't provide any significant benefit.
