cmd/bench: wait for load average to drop before starting

The coordinator runs tests on a freshly booted VM which may still be
running background boot tasks when bench starts.

For minimal noise, wait for the system load average to drop (indicating
background tasks have completed) before continuing with benchmarking.

For golang/go#49207.
