Use fast: true option in all benchmarks.

This prevents get_physical_time from being invoked in the wait_until function in reactor_threaded.c. The overhead of that call to get_physical_time appears to be as much as 10% of total cycles in benchmarks like PingPong whose execution times are dominated by runtime overhead.
