FilepathGlob hung when a symlink pointed at a parent directory. Track visited inodes via os.SameFile and do not recurse into a directory a second time. Fixes bmatcuk#104

A symlink to a parent directory made ** walk forever.
Mark each directory after Stat and skip it if os.SameFile says we have already been there. FilepathGlob("link-to-parent/") and FilepathGlob("") in a tree with such a link now return.
Fixes #104
