perf lock: Add lock aggregation enum
Introduce the aggr_mode variable to prepare a later code change.
The default is LOCK_AGGR_ADDR which aggregates the result for the lock
instances.
When -t/--threads option is given, it'd be set to LOCK_AGGR_TASK. The
LOCK_AGGR_CALLER is for the contention analysis and it'd aggregate the
stat by comparing the callstacks.
