or1k: add F_{DUPFD_CLOEXEC, SETPIPE_SZ, GETPIPE_SZ}

Those definitions exist on all other architectures, but were not
present in or1k specific headers when or1k support was merged.

On the kernel side, their support is completely architecture
independent, so we just need those definitions to make those fcntl()
calls available on or1k.
