Enable symlink_link_linkinfo_is_link_* tests on Windows

We mark symlink_link_linkinfo_is_link_error2.phpt as XFAIL on Windows
ZTS.  Several Windows API file system functions ignore trailing spaces
in absolute filenames after the final directory separator, which causes
`link(' ', $link)` to actually call `CreateHardLink()` which then
fails, because linking folders is not supported.  However, with NTS
builds (as well as on other systems), the $target is found to not
exist, so the function fails without actually attempting to create the
link.  This needs further investigation.
