pgbench: Avoid unnecessary measurement of connection delays.

Commit 547f04e734 changed pgbench so that it used the measurement result
of connection delays in its benchmark report only when -C/--connect option
is specified. But previously those delays were unnecessarily measured
even when that option is not specified. Which was a waste of cycles.
This commit improves pgbench so that it avoids such unnecessary measurement.

Back-patch to v14 where commit 547f04e734 first appeared.
