Log:
[NTFS]
- In NtfsQueryDirectory(), don't upcase name in dir search pattern, it can conflict
with POSIX names.
- In CompareFileName(), handle the fact that for Win32 & DOS we do case insensitive
comparisons by upcasing name before match. Don't do it for POSIX names!

This fixes name completion in cmd for POSIX. And doesn't break it for Win32 :-).
