[LLDB][TestSuite] Improve skipIfWindowsAndNonEnglish in decorators.py

[aganea]

Summary

Improve rG79809f58b02419a5d1bfb6c9a59dbd13cd038c77 as suggested by @ted :

"if lldbplatformutil.getPlatform() != "windows": will check if the lldb platform is windows; this won’t be true if running embedded lldb tests on windows. Since we want to see if the host is windows, better to say if sys.platform != "win32":"
