 longer before launching client, as some of the slower build types (as with
 TSAN enabled) sometimes result in executing it before the server has prepared

Subject: [PATCH 22/23] GitHub CI pipeline: `transport_test` (scripted) script
 needs to wait longer before launching client, as some of the slower build
 types (as with TSAN enabled) sometimes result in executing it before the
 server has read the input-script fully; so the test does not execute (fails).
 Increase all similar wait times a bit. / Pulling in submodules (i_t_s -> main
 merge).
