[PATCH v2] perf python: include "util/sample.h"

[Xu Yang <xu.yang_2@nxp.com>]

The 32-bit arm build system will complain:

tools/perf/util/python.c:75:28: error: field ‘sample’ has incomplete type
   75 |         struct perf_sample sample;

However, arm64 build system doesn't complain this.

The root cause is arm64 define "HAVE_KVM_STAT_SUPPORT := 1" in
tools/perf/arch/arm64/Makefile, but arm arch doesn't define this.
This will lead to kvm-stat.h include other header files on arm64 build
system, especially "util/sample.h" for util/python.c.

This will try to directly include "util/sample.h" for "util/python.c" to
avoid such build issue on arm platform.
