Bug#529074: crash when compiled with -D_FORTIFY_SOURCE=2

Hello!

When compiled with hardening-wrapper[1] enabled (or compiled with
Ubuntu's compiler), nvram-wakeup will always crash due to a 1-byte buffer
overflow in the xxd() function.  The attached patch solves the problem.

Upstream bug report: https://sourceforge.net/tracker/?func=detail&aid=2782757&group_id=35022&atid=412755

Thanks!
