[PATCH 2/4] overlay/017: use t_dir_type to find file by d_ino

[Amir Goldstein <amir73il@gmail.com>]

'find -ino' is this test was supposed to filter files by inode number
that was recorded with 'ls -i' to compare st_ino returned by stat(2)
with d_ino returned by getdents64(2).

It turns out that on some systems, 'find -ino' uses stat(2) for
filtering by inode number, which is not what we want.

Use the auxiliary program t_dir_type to filter files by inode number
instead.
