perf tools: Add cpu to struct thread
Tools may wish to track on which cpu a thread is running. Add 'cpu' to
struct thread for that purpose.
This will be used to determine the cpu when decoding a per-thread
Instruction Trace.
E.g: Intel PT decoding uses sched_switch events to determine which task
is running on which cpu. The Intel PT data comes straight from the
hardware which doesn't know about linux threads.
