If not given the -o/--output option, git archive writes the archive to
stdout. This proves unhelpful if not redirected or piped somewhere.
Rather than spewing binary at the user's terminal, die with an
appropriate message.

I considered adding a -f/--force option, like gzip has, but writing an
archive to a tty seems like a sufficiently insane use case that I'll let
whoever actually needs that write the patch for it. ;)
