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

[Jonathan Wakely <jwakely@redhat.com>]

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.
