mtd: example job file

This job file shows how one can write sequentially to an MTD device,
erase (with trim), and do a looped write/trim workload. Ignoring EIO
errors allows operations to continue as bad blocks are skipped.
The block histogram counts P/E cycles and can be used to assess
NAND flash lifetime and failure characteristics. The job file is
written to work with the nandsim fake NAND device.
