Remove broken code to replace st_mode value with ACCESSPERMS when lstat(2) is called on symlinks -- this code appears never to have worked.  The PR this addresses suggests that the intended original behavior is the right one, but as bde points out in the PR comments, we do actually support storing a mode on symlinks, so returning it seems reasonable.

This is consistent with Mac OS X, which despite documentation to
the contrary does return the mode set on a symlink, but not some
other platforms.  The Single Unix Spec requires only that the
returned bits be "meaningful", which seems at best unhelpful as
advice goes.
