btrfs-progs: convert-tests: Add test for backup superblock migration
New convert framework uses new and simpler chunk layout, while the cost
is the more complex superblock range migration logical, compared to old
convert.
Enhance the convert test script to create file which will takes up 2nd
backup superblock space, to ensure the superblock migration is working
as expected.
