Improve PEP 383 tests (in test_os)
* Use the current filesystem encoding instead of always using utf-8
* Enable the test on Mac OS X
* Use TESTFN_UNENCODABLE and TESTFN_UNICODE instead of arbitrary filenames
* To decode a filename, use strict error handler instead surrogateescape for
mbcs encoding (on Windows)
* Use TESTFN_UNENCODABLE (if available) for the directory name
Skip the test if no non-ascii filename can be created.
