Make strnlen() visible in old versions of glibc
Strnlen() is in POSIX 2008 but was a GNU extension up to glibc 2.10 requiring to define _GNU_SOURCE. This fixes compilation on CentOS 4.9. Also, move our implementation of strnlen() that was added to support DJGPP to helpers.c. Corresponding to flashrom svn r1878.
