[PATCH 2/2] perf: Fix missing strndup declaration

[Frederic Weisbecker <fweisbec@gmail.com>]

<ctype.h> is included first without _GNU_SOURCE, so it ends up
including <string.h> without declaring strndup(). And further
<string.h> declarations, even with _GNU_SOURCE defined, are
of course without effect.

Therefore:

	util/strfilter.c: Dans la fonction «strfilter_node__new» :
	util/strfilter.c:134: attention : déclaration implicite de la fonction « «strndup» »
	util/strfilter.c:134: attention : incompatible implicit declaration of built-in function «strndup»
	make: *** [util/strfilter.o] Erreur 1

Just don't include ctype.h as it doesn't appear to be necessary
anyway.
