Amir Goldstein 5f49f15cf4 overlay: test creating lower hardlinks for copied up files
kernel v4.13 introduced the index=on feature for not breaking
hardlinks on copy-up.  With the index feature enabled a regression
was introduced - lower files that are hardlined while overlay is
offline can result in lookup error after overlay in mounted.

The regression was fixed by upstream commit
  6eaf011144af ovl: fix EIO from lookup of non-indexed upper
that was merged to v4.14-rc7.

This test verifies that behavior is sane after creating lower
hardlinks for copied up files while overlayfs is offline.
