In overlay/031, it only cover the test case of whiteouts in origined upper dir. This patch add two cases cover the 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).

# The unmerged and origined directories may contain invalid
|
|
# whiteouts when we change underlaying dir (e.g. clean up lowerdir)
|
|
# and remount overlay. This may lead to whiteouts exposure and
|
|
# rmdir failure.
