Reset task priority when spawning a passive translator

succeed when the server is privileged. This priority is currently
inherited by child tasks, which could be passive translators owned by
unprivileged users. Reset the priority of the task used for translator
instantiation.

new task priority to 25 (BASEPRI_USER).
