The three functions for reading cwd, exe and root symlinks of processes already share a common core: get_process_link_contents(). Let's refactor that a bit, and move formatting of the /proc/self/ path into this helper function instead of doing that in the caller, thus sharing more code. While we are at it, make the return parameters optional, in case the information if the links are readable is interesting, but the contents is not. (This also means safe_getcwd() and readlinkat_malloc() are updated to make the return parameter optional, as these are called by the relevant three functions)
