dir-iterator: add tests for dir-iterator API

Browse Source 
Create t/helper/test-dir-iterator.c, which prints relevant information
about a directory tree iterated over with dir-iterator.

Create t/t0066-dir-iterator.sh, which tests that dir-iterator does
iterate through a whole directory tree as expected.
