When clone is populating the working tree, it ignores the
return status from unpack_trees; this means we may report a
successful clone, even when the checkout fails.
When checkout fails, we may want to leave the $GIT_DIR in
place, as it might be possible to recover the data through
further use of "git checkout" (e.g., if the checkout failed
due to a transient error, disk full, etc). However, we
already die on a number of other checkout-related errors, so
this patch follows that pattern.
In addition to marking a now-passing test, we need to adjust
t5710, which blindly assumed it could make bogus clones of
very deep alternates hierarchies. By using "--bare", we can
avoid it actually touching any objects.

I think the "leave the data behind" fix may be to just set "junk_pid =
0" a little sooner in cmd_clone (i.e., before checkout()). Then we
would still die, but at least leave the fetched objects intact.
