fs-tests: integck: add -e option to verify operations
Improve the test and add -e option which forces integck to verify all operation it performs. This patch does not implement file writes and holes operations so far - will be done in subsequent patches. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
