Update Ceres to latest upstream version 2.1.0temp-ceres_update

This release deprecated the Parameterization API and the new Manifolds
API is to be used instead. This is what was done in the Libmv as part
of this change.

Additionally, remove the bundling scripts. Nowadays those are only
leading to a duplicated work to maintain.
