Jilles Tjoelker 8bf4902569 diff: Correct fd 0 case on pipe ...

After git commit c8d40bf8ec, if fd 0 was
not open, it is left with CLOEXEC set and therefore fails. This is an
unlikely situation, but fixing it reduces the size of the code (by using
posix_spawn_file_actions_adddup2's special case if the two file
descriptor numbers are the same).

At the same time, check the error code from
posix_spawn_file_actions_adddup2.
