To test read workload behavior with zonemode=zbd and zoned block devices
with all zones empty, it is required to write data to the device before
the read workload. To avoid repeated codes for such test preparation,
introduce the helper function write_and_run_one_file_job(). It runs the
write job with specified offset and size to prepare the read data, then
run the specified job for read test.
