iotests: Improve _filter_qemu_img_map
Although _filter_qemu_img_map documents that it scrubs offsets, it was only doing so for human mode. Of the existing tests using the filter (97, 122, 150, 154, 176), two of them are affected, but it does not hurt the validity of the tests to not require particular mappings (another test, 66, uses offsets but intentionally does not pass through _filter_qemu_img_map, because it checks that offsets are unchanged before and after an operation). Another justification for this patch is that it will allow a future patch to utilize 'qemu-img map --output=json' to check the status of preallocated zero clusters without regards to the mapping (since the qcow2 mapping can be very sensitive to the chosen cluster size, when preallocation is not in use).
