[PATCH v2] overlay/081: add missing _require_scratch check

[Prabhakar Pujeri <prabhakar.pujeri@dell.com>]

The test runs _scratch_mkfs without first requiring a scratch device, so it fails messily instead of skipping when no scratch device is configured.  Add _require_scratch so the test skips cleanly when no scratch device is present.
