Print paths when non-ghar symlinks encountered

Added extra path information when a non-ghar symlink is found so that user can understand where the problem is.

Before this commit it read: ".bashrc: can't handle non-ghar symlinks."
After this commit it reads: "Linking ~/.bashrc to ~/Projects/ghar/ghar/.bashrc: can't handle non-ghar symlinks."
