Avoid PLT when calling __sched_getaffinity_new
This patch adds an internal entry for __sched_getaffinity_new so that
__sched_getaffinity_old calls __sched_getaffinity_new without going
through PLT.
[BZ #18822]
* sysdeps/unix/sysv/linux/sched_getaffinity.c
(__sched_getaffinity_new): Add libc_hidden_proto and
libc_hidden_def.
