When runcppunittest (resp. |mach cppunittest|) is passed a directory, it attempts to indiscriminately run all the files found in that directory. This is unhelpful, as directories containing compiled cppunittests also tend to have other things: Makefiles, object files, etc. Let's filter out non-executable files from the directory listing and make the user experience more pleasant.
