This aligns bits/sched.h onto sysdeps/unix/sysv/linux/bits/sched.h:
define __sched_param instead of SCHED_* and sched_param when
<bits/sched.h> is included with __need_schedparam defined.
* bits/sched.h [__need_schedparam] (SCHED_OTHER, SCHED_FIFO, SCHED_RR,
sched_param): do not define.
[!__defined_schedparam && (__need_schedparam || _SCHED_H)]
(__defined_schedparam): Define to 1.
(__sched_param): New structure, identical to sched_param.
(__need_schedparam): Undefine.
