[PATCH] perf: fix perf_event.h header usage

[Stephane Eranian <eranian@google.com>]

This patch fixes the usage of the perf_event.h header file
between command modules and the supporting code in util.

It is necessary to ensure that ALL files use the SAME
perf_event.h header from the kernel source tree.

There were a couple of #include <linux/perf_event.h> mixed
with #include "../../perf_event.h".

This caused issues on some distros because of mismatch
in the layout of struct perf_event_attr. That eventually
led perf stat to segfault.
