    base-files: ignore "mesg n" error messages
    
    When using "su - myuser" to change from root to a non-privileged user,
    "mesg n" from the default .profile fails with "mesg: error: tty device
    is not owned by group `tty' or "mesg: cannot open /dev/ttyS0:
    Permission denied", depending on whether mesg comes from busybox or
    util-linux.
    
    This does not happen during a normal login because permissions on
    /dev/tty* get changed while doing that, something that isn't possible
    with plain "su -".
    
    As the error can't be avoided and failures of mesg probably aren't
    particularly important, now error messages get dumped to /dev/null.
