When stdout or stderr (but not both) are redirected and PYTHONIOENCODING is not set, test_sys is failed in 2.7.

FAIL: test_43581 (test.test_sys.SysModuleTest)
Traceback (most recent call last):
  File "/home/serhiy/py/cpython2.7-debug/Lib/test/", line 415, in test_43581
    self.assertTrue(sys.__stdout__.encoding == sys.__stderr__.encoding)
AssertionError: False is not true


Can be reproduced by one of following commands:

$ ./python -m test.regrtest -v test_sys | cat
$ ./python -m test.regrtest -v test_sys 2>/dev/null

Proposed patch fixes the test.
