[PATCH 3/4] overlay: consider index dir with whiteouts clean

[Amir Goldstein <amir73il@gmail.com>]

Several tests check that index dir is empty after upper entries have
been unlinked. With nfs_export=on, index will contain a whiteout index
entry in that case so, allow chardevs when checking for clean index dir.
