Stabilize 026_overwrite_contrecord test
On slow machines, this test can take long enough to generate WAL that a
time-based checkpoint occurs before the primary is stopped. If the
checkpoint record is written to the tail WAL segment that the test later
removes, a standby initialized from the resulting backup tries to read
the missing checkpoint record and fails with a PANIC during startup.
This caused the test to fail on buildfarm member skink.
Fix this by setting checkpoint_timeout high enough to prevent unrelated
checkpoints during the test. This follows the approach used by other
recovery tests, such as 043_no_contrecord_switch.pl, that depend on a
specific WAL layout.
Backpatch to all supported versions.
