Subject: [PATCH 1/1] perf tools: Fix build break on powerpc

From: Sukadev Bhattiprolu <sukadev@...ux.vnet.ibm.com>

Commit 531d2410635c ("perf tools: Do not include stringify.h from the
kernel sources") seems to have accidentially removed the inclusion of
"util/header.h" from "arch/powerpc/util/header.c".

"util/header.h" provides the prototype for get_cpuid() and is needed to
build perf on Powerpc:

	arch/powerpc/util/header.c:17:1: error: no previous prototype for 'get_cpuid' [-Werror=missing-prototypes]

[ Included "util.h" too, to get the scnprintf() prototype ]
