btrfs-progs: tests: add case to handle deprecated inode cache in check

The inode_cache and involved on-disk formats are deprecated and will
have no effect since v5.11 kernel.

And in v6.11 kernel, new tree-checker will even reject data extents
belonging to those deprecated inode cache.
Lowmem check can detect such deprecated inode cache from the beginning.

This images are generated by 5.10 LTS kernels with inode cache.
