hd-geo-test: Add tests for lchs override
Add QTest tests to check the logical geometry override option. The tests in hd-geo-test are out of date - they only test IDE and do not test interesting MBRs. Creating qcow2 disks with specific size and MBR layout is currently unused - we only use a default empty MBR.
