Remove forced CONFIG from find_package(Eigen3)

- Ceres will fail to configure if Eigen3::Eigen target is not found, and
  the minimum required Eigen version specified (3.3) exports Eigen as
  a CMake package and this is reflected in the default Ubuntu 18.04
  packages.
- This permits users to specify their own Eigen3 detection should they
  choose to do so, but they must do so via an imported target.
