testsuite: Work around #12554
It seems that Python 2.7.11 and "recent" msys2 releases are broken, holding open file locks unexpected. This causes rmtree to intermittently fail. Even worse, it would fail silently (since we pass ignore_errors=True), causing makedirs to fail later. We now explicitly check for the existence of the test directory before attempting to delete it and disable ignore_errors. Moreover, on Windows we now try multiple times to rmtree the testdir, working around the apparently msys bug. This is all just terrible, but Phyx and I spent several hours trying to track down the issue to no available. The workaround is better than nothing.
