Use per-query timeout in subscription test

A buildfarm failure in subscription/038_walsnd_shutdown_timeout was
diagnosed to the background psql session timing out due to a backup
taking a long time. The session was using a single timeout for all
queries, so switch to resetting the timer for each query to make it
survive slow backups due to constrained buildfarm machines.

Backpatch to v19 where the test was introduced.
