address cuserid() issue on BG/Q

The current BG/Q environment doesn't support cuserid(), which Darshan uses to identify the userid for each job. There is a ticket open with IBM to track this issue. If IBM doesn't address it, our fallback plan on BG/Q will be to use the $USER environment variable, and possibly hash it to generate a unique numerical id for each user.
