Bug description:lchown fails to change ownership of symlink with ZTS

Description:
------------
Compiling PHP with ZTS affects performance of lchown and lchgrp. 

PHP CLI compiled without ZTS:

./configure --disable-all

ZTS is above + '--enable-maintainer-zts'

Test script:
---------------
<?php
   echo "TS: ", PHP_ZTS, "\n";
   is_link("foo") && unlink("foo");
   symlink("/tmp", "foo");
   lchown("foo", 99);
   var_dump(lstat("foo")['uid']);
?>

Expected result:
----------------
TS: 1
int(99)

Actual result:
--------------
TS: 1
int(0)
