integrate "source" use case to bench_qdir_tree

Although there's already some real source (4.6.0 file list) in the test,
we decided it's useful to still have this benchmark for a standard directory
structure in the 1000 file test.
The source benchmark is 10 directories, each containing 10 subdirectories,
which each contain 10 files.
