Update Bazel WORKSPACE for newest Bazel

The latest Bazel releases have deprecated Bazel-native
"http_archive()" directive in favor of a Skylark version.
This updates the WORKSPACE to use the new format, as well
as removing the Eigen BUILD in favor of a string in the
WORKSPACE.

Fixes: https://github.com/ceres-solver/ceres-solver/issues/463
