Remove time limit of temporary WSS override on debuggable builds

Bug: 341964702
Test: On device, can override for a long period on an eng build. Per hackz@'s request, also verified from the logs that the service name can be overridden on a user build, which suggests that the time limit was not put in specifically to limit override in debuggable builds.
