It fixes a problem (in JEP380) on Windows where some file operations on Unix domain sockets were not working and led to the feature being disabled on Windows 2019 Server in JDK 16. So, the fix re-enables the feature on all versions of Windows that support it.

The change touches the code that handles symbolic links in Windows (since they are implemented as NTFS reparse points, like Unix sockets), but I didn't add any specific testing in this area, as I assume the existing unit tests for NIO symbolic links should cover that. If I should add more tests here, then I can do that.
