real_path(): properly handle nonexistent top-level paths
The change has two points: 1. Do not strip off a leading slash, because that erroneously turns an absolute path into a relative path. 2. Do not remove slashes from groups of multiple slashes; instead let chdir() handle them. It could be, for example, that it wants to leave leading double-slashes alone.
