workspace directory is created for a TestRuntest environment.
The superclass TestCommon.__init__() will change directory (chdir)
to the workspace directory, so an explicit "chdir = '.'" on all
of the run() method calls is not necessary. This initialization
also copies the runtest.py and testing/framework/ subdirectory tree to the
temporary directory, duplicating how this test infrastructure
appears in a normal workspace.
