Do not munge contents of local symbolic links
This lets Emacs deal with arbitrary local symlinks without
mishandling their contents (Bug#28156). For example,
(progn (shell-command "ln -fs '~' 'x'") (rename-file "x" "/tmp/x"))

Formerly, it did that only if the working directory was on the
same filesystem as /tmp; otherwise, it expanded the '~' to
the user's home directory.
