[PATCH libpciaccess 5/5] linux: Remove no longer needed _GNU_SOURCE define.

[Emil Velikov]

With earlier commit we're including config.h before the system headers.
As such we no longer require the extra define as it is handled/set via
AC_USE_SYSTEM_EXTENSIONS. Note platforms which do not use autotools but
require the define (such as Android) might need to set it explicitly.
