[PATCH v4 2/8] engines: sync: add support for DDIR_SYNCFS

Flag the sync IO engine with the FIO_SYNCFS flag to indicate that syncfs
operations are supported. No additional changes are needed to enable
syncfs processing as this IO engine already processes all sync operation
variants using do_io_u_sync().
