posix-cpu-timer: Unify the now redundant code in lookup_task

Browse Source 
Now that both !thread paths through lookup_task call
thread_group_leader, unify them into the single test at the end of
lookup_task.

This unification just makes it clear what is happening in the gettime
special case of lookup_task.
