Fixes #23520. Replaces #23555. The problem started withcdf370626fand90b1ec03b2which together started printing the wall message in more cases. The motivation for those change was reasonable, but this clearly causes problems described in #23520: users are getting unexpected wall messages. Xterm, urxvt, (anything using libutempter?), and tmux (in some configurations), register local pty sessions in utmp. So let's try to suppress the message for local pseudo-terminal logins. This patch based on #23538, but instead of filtering just on /dev/pts, it uses the .ut_addr_v6 to only filter out local entries.
