btrfs-progs: tests: convert: add a test case to check the csum for the image file

Browse Source 
The new test case would create an empty ext4 with 64K block size, which
can lead to a new data chunk which is no longer 1:1 mapped.

Then convert the fs and verify it with --check-data-csum to make sure
the image file is fine.
