Don't unpack delta chains while writing a pack from a pack v1 index
We only need to inflate the delta to verify the content is sane;
going all the way through the delta chain by getCachedBytes is
a massive expensive that we just cannot afford to pay. This
simple change improves clone time for the Linux kernel from
14m50s to 3m20s, due to the improved throughput in our write
objects phase.
