Fix bug #61990 ext\spl\examples\tests\dualiterator_001.phpt fails

This fixes a general issue. In this ticket and not for the first time
is being seen, that people are trying to use data from "examples"
in the tests. When extracting a test pack only "tests" and its siblings
was taken into account. Now "examples" are copied as well.
