Increase waited-at time precision

[Baron Schwartz]

Can we increase the precision here from %.2f to something more like %.6f or even more? This is in innobase./sync/sync0arr.c:

   fprintf(file,
"--Thread %lu has waited at %s line %lu for %.2f seconds the semaphore:\n",
         (ulong) os_thread_pf(cell->thread), cell->file,
             (ulong) cell->line,
             difftime(time(NULL), cell->reservation_time));
