[issue25703] test_sys is failed if standard stream is redirected in 2.7

[Serhiy Storchaka]

New submission from Serhiy Storchaka:

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/test_sys.py", 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.
