If our pack-objects sub-process dies of a signal, then it
likely didn't have a chance to write anything useful to
stderr. The user may be left scratching their head why the
push failed. Let's detect this situation and write something
to stderr.

We could drop the SIGPIPE special-case, but I think it's just noise
after the unpack-status fix in the previous commit.
