execute: check whether the specified fd is a tty before chowning/chmoding it (#3457)
Let's add an extra safety check before we chmod/chown a TTY to the right user, as we might end up having connected something to STDIN/STDOUT that is actually not a TTY, even though this might have been requested, due to permissive StandardInput= settings or transient service activation with fds passed in.
