[PATCH v4 7/8] engines: ftruncate: add support for DDIR_SYNCFS

[Damien Le Moal <dlemoal@kernel.org>]

Flag the ftruncate IO engine with FIO_SYNCFS to indicate that it
supports the syncfs operation. Also change fio_ftruncate_queue() to use
ddir_sync() to include all variants of the sync operation for driving
the call to do_io_u_sync(), instead of testing for DDIR_SYNC only as
that leads to ignoring other sync variants.
