client/server: enable "All clients" latency percentiles

The ?lat_percentile toggles and list of percentiles to report from the
thread_stat payload have not been propagated to the overall summary
report. Enable "All clients" latency percentile reporting by arbitrarily
using the toggles and percentile list from the first thread_stat
payload sent from the server.
