perf bench: Fix detached tarball building due to missing 'perf bench memcpy' headers

A change on kernel files included by the 'perf bench memcpy' code grew some new
include deps, breaking the detached tarball build:

  $ make -C tools/perf build-test
  make: Entering directory '/home/acme/git/linux/tools/perf'
  - tarpkg: ./tests/perf-targz-src-pkg .
  tests/make:302: recipe for target 'tarpkg' failed
  make[1]: *** [tarpkg] Error 2
  Makefile:102: recipe for target 'build-test' failed
  make: *** [build-test] Error 2
  make: Leaving directory '/home/acme/git/linux/tools/perf'
  $ cat tools/perf/tarpkg
  ./tests/perf-targz-src-pkg .
    PERF_VERSION = 4.5.g05f5ec
    PERF_VERSION = 4.5.g05f5ec
  In file included from bench/mem-memcpy-x86-64-asm.S:9:0:
  bench/../../../arch/x86/lib/memcpy_64.S:5:29: fatal error: asm/cpufeatures.h: No such file or directory
  compilation terminated.
  mv: cannot stat ‘bench/.mem-memcpy-x86-64-asm.o.tmp’: No such file or directory

  $

Add arch/*/include/asm/*features.h to tools/perf/MANIFEST so that we can
continue to use detached tarballs to build perf.

Now it builds ok, doing it manually:

  $ make help | grep perf
    perf-tar-src-pkg    - Build perf-4.5.0.tar source tarball
    perf-targz-src-pkg  - Build perf-4.5.0.tar.gz source tarball
    perf-tarbz2-src-pkg - Build perf-4.5.0.tar.bz2 source tarball
    perf-tarxz-src-pkg  - Build perf-4.5.0.tar.xz source tarball
  $ ls -la perf-4.5.0.tar
  ls: cannot access perf-4.5.0.tar: No such file or directory
  $ make perf-tar-src-pkg
    TAR
    PERF_VERSION = 4.5.g32c25b
  $ ls -la perf-4.5.0.tar
  -rw-rw-r--. 1 acme acme 6318080 Mar 24 11:52 perf-4.5.0.tar
  $ mv perf-4.5.0.tar /tmp
  $ cd /tmp
  $ tar xf perf-4.5.0.tar
  $ cd perf-4.5.0/tools/perf
  $ make > /dev/null
  PERF_VERSION = 4.5.g32c25b
  $ ls -la perf
  -rwxrwxr-x. 1 acme acme 14046416 Mar 24 11:53 perf
  $ ./perf --version
  perf version 4.5.g32c25b
  $ perf bench
  Usage:
	perf bench [<common options>] <collection> <benchmark> [<options>]

        # List of all available benchmark collections:

         sched: Scheduler and IPC benchmarks
           mem: Memory access benchmarks
          numa: NUMA scheduling and MM benchmarks
         futex: Futex stressing benchmarks
           all: All benchmarks

  $ perf bench mem

        # List of available benchmarks for collection 'mem':

        memcpy: Benchmark for memcpy() functions
        memset: Benchmark for memset() functions
           all: Run all memory access benchmarks

  $ perf bench mem memcpy
