[committed] libstdc++: Adjust Filesystem TS test for Windows

[Jonathan Wakely via Gcc-patches]

Tested x86_64-linux and x86_64-w64-mingw, pushed to trunk.


The Filesystem TS isn't really supported for Windows, but the FAIL for
this test is just because it doesn't match what happens on Windows.

libstdc++-v3/ChangeLog:

        * testsuite/experimental/filesystem/operations/create_directories.cc:
        Adjust expected results for Windows.
