Subject: util: always enforce O_NOCTTY and O_CLOEXEC in openpt_in_namespace()

The child process is shortliving, hence always set O_NOCTTY so that the
tty doesn't quickly become controlling TTY and then gives it up again.
Also set O_CLOEXEC, because it's cleaner, and doesn't affect the parent
anyway.
