runtime/pprof: speed up CPU profiling shutdown
The core CPU profiling loop contains a 100ms sleep.
This is important to reduce overhead.
However, it means that it takes 200ms to shutting down a program
with CPU profiling enabled. When trying to collect many samples
by running a short-lived program many times, this adds up.
This change cuts the shutdown penalty in half by skipping
the sleep whenever possible.
