doc: fix realpath index entry

The 'readlink' node has '@findex realpath' in it. This results in
    info doc/coreutils.info realpath
incorrectly jumping to the 'readlink' node (instead of the 'realpath'
node). Change it to @cindex instead.

* doc/coreutils.texi (readlink): Change '@findex realpath' to @cindex.
