add operator__name__ test

The builtin functions in the `operator' module are missing their
__name__ attribute, which is causing some of the imported CPython
regression tests to fail.

test/tests/operator__name__.py

+# expected: fail
+import operator

+for op in sorted(dir(operator)):
+    if op.startswith("_"):
+        continue
+    print getattr(operator, op).__name__
