The contents of a symlink is the path to which it points. We can simply read the contents as a new path, and use `getEntry` to get the contents of the symbolic link. This implementation should also fully traverse any path that is a series of symbolic link. This does allow for a DoS attack by creating a recursive symbolic link cycle (e.g. `a` -> `b` -> `a`). Fixes: swiftlang#7081

we should avoid using fatalError which would crash the program. see #7096
