Add two tests of whiteout check in origin dir, cover other
two situations:

1) Lower origined dir have whiteouts;
2) Both upper and lower origined dirs have whiteouts (although
this case is pass now, still add this to cover all three kinds
of situations).

V2:
factor out _create_whiteout() helper,
test whiteout in the middle layer,
fix test failure with inodes index feature.
