test_existence.sh: use /usr/include/c++ as test data source

We want a deep tree with many files and directories.  dfilemaker1 creates only
a flat tree with all files in one directory.

Instead, copy from /usr/include/c++ which should be reasonably large and
in terms of file count, and have some depth to the tree, on
any installation.
