btrfs-progs: test: Add image for quota verify stack overflow
For image with tree reloc tree, if its height is over level 2, the root node's backref will point to itself. It's valid for kernel, but quota verify code can't handle it and cause a infinite call, overflowing the stack. Add minimal image to reproduce the bug, as regression test.
