perf tools: Fix compilation on powerpc

Currently, perf fails to compile on powerpc with this error:

     CC util/header.o
 In file included from util/../perf.h:17,
                  from util/header.c:9:
 util/../../../arch/powerpc/include/asm/unistd.h:360:27: error:
 linux/linkage.h: No such file or directory make: ***
 [util/header.o] Error 1

The reason is that we still have a #define __KERNEL__ in effect
at the point where <asm/unistd.h> gets included, which means we
get extra stuff that we don't need or want.

This fixes the problem by undefining __KERNEL__ once we have
included the file for which we need __KERNEL__ defined.
