iotests: Add test of recent fix to 'qemu-img measure'
The new test 190 ensures we don't regress back to an infinite loop when measuring the size of a 2T+ qcow2 image. I did not append to test 178, because that test is also designed to run with format 'raw'; also, this gives us some coverage of the measure command under the quick group.
