Fix the (currently unbuilt) qdir/tree/ benchmark

Browse Source 
It tried to find its test-data-directory locally, instead of asking
FileSystem where it was keeping its files, relative to a temporary
directory. Its expected counts didn't match the arcane results of its
data file; since this is a benchmark, not a regression test, I'm
assuming that's just because it was never right or the rules for
QDirIterator's filtering have changed.

Tidied up somewhat in the process.
