terminal-util: open /dev/null with O_CLOEXEC in make_stdio_null()
Ultimately, O_CLOEXEC should be off in fd 0, 1, 2, but when we open /dev/null here it's unlikely to be < 0, and after dupping the fd to 0, 1, 2 we turn off O_CLOEXEC explicitly anyway. Unless we know that what we are about to open will return 0, 1 or 2 we should always set O_CLOEXEC in order to be safe to other threads forking of subprocesses at the wrong moment.
