[NTFS]
- Implement GetBestFileNameFromRecord() which will select the higher subsystem name available (POSIX -> Win32 -> DOS) and return it
- Replace the hand-made implementation of it in dirctl functions relying on it (NtfsGetDirectoryInformation(), NtfsGetFullDirectoryInformation(), NtfsGetBothDirectoryInformation())
- Use it in NtfsMakeFCBFromDirEntry()

This fixes browsing POSIX volume (and opening file) in cmd. Even though, explorer doesn't seem to be happy with such change...
This doesn't fix yet the autocompletion in cmd either.
