[PATCH] tools include: Fix wrong macro definitions for cpu_to_le* for big endian

[He Kuang]

From: Wang Nan <wangnan0 at huawei.com>

The cpu_to_le* macros in kernel.h are defined without considering
endianese. This patch includes "byteoder/generic.h" instead to fix the
bug, and removes redundant le64_to_cpu definition in intel-bts.c.
