Anatol Belski bdce007aac performance-metrics: Add QCOW2 overlay tempfile helper ...

Add qcow_overlay_tempfile() which creates a raw backing file with
pre-populated data and a QCOW2 overlay on top with no allocated
clusters.  The overlay is opened with backing file support via
QcowDiskSync so reads fall through to the backing file.

To be used by backing file read and copy-on-write write
benchmarks.
