[patch] rcmd.3: Add missing condition concerning .rhosts file

["Nikola Forró" <nforro-H+wXaHxf7aLQT0dZR+AlfA@public.gmane.org>]

The list of conditions determining if iruserok() and ruserok()
functions automatically fail is incomplete. According to glibc
source code, the functions also fail if the .rhosts file
is hardlinked anywhere.
