`Dir.glob('../*')` shows unexpected result if current directory is a symbolic linked directory on Windows.
This issue seems to be introduced by r44802.

The following is a test case.

C:\foo>mklink /D bar V:\
symbolic link created for bar <<===>> V:\

C:\foo>cd bar

C:\foo\bar>ruby -ve "p Dir.glob('../*')"
