Disable use of archiving in 009_twophase.pl

This partially reverts 68cb5af, as using archiving to enforce the
rename of the last partial segment of the old timeline at promotion to
use .partial as suffix is impacting the tests when it does switchovers.
As showed by the logs gathered by the CI in the tests that failed, a new
standby may fail to find the WAL segment it needs to follow a promoted
instance with its timeline jump, as it got renamed to .partial.

This problem would manifest as a run timeout with 009_twophase.pl, as
the new standby repeatedly requests a segment from the promoted primary
that it would not find.
