readlink(1) on UNC path reports raw WinNT device path instead of UNC path

[aureliencouderc]

Current path (UNC path on OpenText NFS share, ms-nfs41-client or MS WebDAV share):
\\10.49.202.239@NFS@2049\nfsdata\wincoreutilstest

$ /cygdrive/c/Program\ Files/coreutils/bin/readlink.exe -f myfile_lnk
\\?\UNC\10.49.202.239@NFS@2049\wincoreutilstest\myfile

The expected output would be:
\\10.49.202.239@NFS@2049\nfsdata\wincoreutilstest\myfile
