[PATCH v3 3/8] engines: libaio: add support for DDIR_SYNCFS

Flag the libaio engine with the FIO_ASYNCIO_SYNC_SYNCFS flag to indicate
that the syncfs operation is supported, with synchronous processing.
Modify fio_libaio_queue() to call do_io_u_syncfs() for an io_u that has
the DDIR_SYNCFS data direction.
