Subject: perf bench numa: Make sure dprintf() is not defined

When building with clang we get this error:

  bench/numa.c:46:9: error: 'dprintf' macro redefined [-Werror,-Wmacro-redefined]
  #define dprintf(x...) do { if (g && g->p.show_details >= 1) printf(x); } while (0)
          ^
  /usr/include/bits/stdio2.h:145:12: note: previous definition is here
  #   define dprintf(fd, ...) \
             ^
    CC       /tmp/build/perf/tests/parse-no-sample-id-all.o
  1 error generated.

So, make sure it is undefined before using that name.
