block/blkio: use FUA flag on write zeroes only if supported

libblkio supports BLKIO_REQ_FUA with write zeros requests only since
version 1.4.0, so let's inform the block layer that the blkio driver
supports it only in this case. Otherwise we can have runtime errors
as reported in https://issues.redhat.com/browse/RHEL-32878
