Fix pgbench timestamp bugs.
Commit 547f04e changed pgbench to use microsecond accounting, but
introduced a couple of logging and aggregation bugs:
1. We print Unix epoch timestamps so that you can correlate them with
other logs, but these were inadvertently changed to use a
system-dependent reference epoch. Compute Unix timestamps, and begin
aggregation intervals on the boundaries of whole Unix epoch seconds, as
before.
2. The user-supplied aggregation interval needed to be scaled.
Back-patch to 14.
