Subject: [PATCH 2/6] perf inject: Add missing callbacks in perf_tool

I found some events (like PERF_RECORD_CGROUP) are not copied by perf
inject due to the missing callbacks.  Let's add them.

While at it, I've changed the order of the callbacks to match with
struct perf_tool so that we can compare them easily.
