    libthread_xu: Properly inherit the creating thread's sched_priority.
    
    When a new thread is created with the inheritsched attribute set to
    PTHREAD_INHERIT_SCHED, then it must inherit the sched_priority
    scheduling parameter from the creating thread, because POSIX sez:
    
    "The following thread scheduling attributes defined by POSIX.1-2008
    are affected by the inheritsched attribute: [...], scheduling parameters
    (schedparam), [...]"
    
    Also:
    
    "For SCHED_FIFO and SCHED_RR, the only required member of the sched_param
    structure is the priority sched_priority. For SCHED_OTHER, the affected
    scheduling parameters are implementation-defined."
    
    For SCHED_OTHER, it will currently inherit the creating thread's
    sched_priority too. We'll see if that poses a problem.
