[PATCH v3 01/27] tools headers uapi: Update tools's copy of linux/perf_event.h

[Jin Yao]

To get the changes in:

Liang Kan's patch
("perf: Introduce PERF_TYPE_HARDWARE_PMU and PERF_TYPE_HW_CACHE_PMU")

Kan's patch is in review at the moment, but the following perf tool
patches need this interface for hybrid support.

This patch can be removed after Kan's patch is upstreamed.
