Subject: [PATCH for-v6.17] perf test: Fix a build error in x86 topdown test

There's an environment that caused the following build error.  Include
"debug.h" (under util directory) to fix it.

  arch/x86/tests/topdown.c: In function 'event_cb':
  arch/x86/tests/topdown.c:53:25: error: implicit declaration of function 'pr_debug'
                                         [-Werror=implicit-function-declaration]
     53 |                         pr_debug("Broken topdown information for '%s'\n", evsel__name(evsel));
        |                         ^~~~~~~~
  cc1: all warnings being treated as errors

Fixes: 5b546de9cc177936 ("perf topdown: Use attribute to see an event is a topdown metic or slots")
