test/nvme: enable BPF traces for bdevperf performance tests

Browse Source 
Enable BPF traces only for bdevperf for now, as it's
easiest to do thanks to "-z" option (wait for RPC before
starting the workload).

Other performance tools will come later - workloads start
immediately and enabling traces will need more thought.
