Use O_CLOEXEC in more places (BZ #15722)
When opening a temporary file without O_CLOEXEC we risk leaking the file descriptor if another thread calls (fork and then) exec while we have the fd open. Fix this by consistently passing O_CLOEXEC everywhere where we open a file for internal use (and not to return it to the user, in which case the API defines whether or not the close-on-exec flag shall be set on the returned fd).
