[bazel] Add fixes for --incompatible_load_cc_rules_from_bzl (#351)

* [bazel] Add fixes for --incompatible_load_cc_rules_from_bzl

Starting with Bazel 1.0 (September 2019), C++ rules will need to be
loaded from the @rules_cc repository. This change adds the required
loads for that. For full compatibility, we will need versions of
googletest and google-benchmark that also includes these loads.

* Run buildifier again after merge
