This is needed to support the kernel regression fix commit 0be0bfd2de9d
("ovl: fix regression caused by overlapping layers detection").
Overlayfs mount is not supposed to fail due to upper/work dir in-use
by other mount unless option index=on is enabled.
Add test variants for index=on and index=off.
Fix some wrong comments and clean noise lines in golden output.

Add tests for overlayfs mounts with:
- Same upperdir/lowerdir
- Overlapping upperdir/lowerdir
- Overlapping lowerdir layers
- Overlapping lowerdir with other mount upperdir/workdir
Add test for moving layer into another after mount.
Overlapping layers on mount or lookup results in ELOOP.
Overlapping lowerdir with other mount upperdir/workdir
result in EBUSY.
