* Fix buffer tracing synchronization lock
- PR #529 (in rocprofiler-sdk-internal) introduced waiting on the syncer flag when emplacing in a buffer to prevent the overwriting buffer records currently being processed in a buffer flush callback
- The above fix introduced a block on the both buffers when a buffer flush callback was being executed instead of a block on the buffer being flushed.
* Add rocpd tests for duplicate records
* Address code review comments
