Fix aio system call wrappers in librt.

- Update aio_return/waitcomplete wrappers for the ssize_t return type.
- Fix the aio_return() wrapper to fail with EINVAL on a pending job.
  This matches the semantics of the in-kernel system call.  Also,
  aio_return() returns errors via errno, not via the return value.
