fs/ntfs3: Fix directory element type detection
Calling stat() from userspace correctly identified junctions in an NTFS
partition as symlinks, but using readdir() and iterating through the
directory containing the same junction did not identify the junction
as a symlink.
When emitting directory contents, check FILE_ATTRIBUTE_REPARSE_POINT
attribute to detect junctions and report them as links.
