Revert "Save cookies back to jar when fetching clone.bundle"

This reverts commit 4abf8e6ef8.

The curl process for updating the cookie file is not atomic.  When
fetching many bundles in parallel, we can sometimes corrupt the file
causing it to be cleared.  Since users should manage gitcookies on
their own, leave it read-only.
