Title: Update gitmodules to use read-only git refs instead of the read-write ones.

If you're installing cf-release on a system without a public_key that is
registered to a github account, `git submodule update` can fail due to
permission denied on the ssh. Updating the submodules to use the
read-only only git URL avoids this.
