    perf: fix build with kernel older than 4.8
    
    * perf is failing to build for me since this oe-core commit:
      commit 9b38c824961fc9dce51bda95c25dac91a69fc64f

        perf: make a copy of kernel source to perf workdir
    
      the problem is that perf sources in kernel older than 4.8 (in my case
      4.4) are depending on the "global" include headers outside tools
      directory, e.g. swab.h in:
      kernel-source/tools$ git grep swab.h
      perf/MANIFEST:include/linux/swab.h
      perf/MANIFEST:include/uapi/linux/swab.h
      perf/util/include/asm/byteorder.h:#include "../../../../include/uapi/linux/swab.h"
    
      this was resolved in 4.8 with:
      commit 7e3f36411342a54f1981fa97b43550b8406a3d69
      Author: Arnaldo Carvalho de Melo <acme at redhat.com>
      Date:   Mon Jul 18 17:42:16 2016 -0300
    
        perf tools: Remove tools/perf/util/include/asm/byteorder.h
    
        Not used anymore. This also stops include linux/swab.h directly
        from the kernel sources, remove that reference from the MANIFEST.
    
      and few more changes to make tools/include more complete and standalone:
      tools/include in 4.15:
      asm  asm-generic  linux  tools  trace  uapi
    
      tools/include in 4.4:
      asm  asm-generic  linux  tools
    
      but copying the include header even for kernels which don't really
      need it doesn't add big overhead, so just copy include to perf sources
      for all kernels.
