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.
