Fixed #11615 -- Changed test runners to use an exit status code of 1 for any number of failed tests.  The previous behavior of using an exit status code equal to the number of failed tests produced incorrect exit status codes when the number of test failures was 256 or greater.  Thanks to lamby for the report and patch.

+Test runner exit status code
+----------------------------
+
+The exit status code of the test runners (``tests/runtests.py`` and ``python
+manage.py test``) no longer represents the number of failed tests, since a
+failure of 256 or more tests resulted in a wrong exit status code.  The exit
+status code for the test runner is now 0 for success (no failing tests) and 1
+for any number of test failures.  If needed, the number of test failures can be
+found at the end of the test runner's output.
