[PATCH v1] binder: transaction latency tracking for user build

[Frankie Chang]

Record start/end timestamp to binder transaction.
When transaction is completed or transaction is free,
it would be checked if transaction latency over threshold (2 sec),
if yes, printing related information for tracing.
