[sheepdog] [PATCH v3 1/3] tests/functional: add a new test for vdi check with the condition nr_zones < inode->nr_copies

[Hitoshi Mitake]

From: Hitoshi Mitake <mitake.hitoshi at lab.ntt.co.jp>

The newly added test checks that "dog vdi check" can check and recover
lost inode objects well under the condition of nr_zones <
inode->nr_copies. Previous "dog vdi check" rises panic in such a case.
