oauth: Apply bgconn timeout per query in 001_server

The background psql session in oauth_validator/001_server lives
for most of the test but its timer was never restarted. On slow
or loaded buildfarm animals the tests can exceed timeout_default
and the next query fails with "IPC::Run: timeout on timer #1".
Fix by restarting the timer per query. Backpatch to v18 where
the test was introduced.
