Subject: [PATCH] Blacklist all WELL_KNOWN_PROTOS from Bazel C++ code
 generation.

This prevents the Bazel `CcProtoAspect` from generating and linking
C++ object code for these files. Without this blacklist, symbols for
protobuf types depended on by `libprotobuf` may be defined multiple
times and violate the ODR rule.

Fixes https://github.com/google/protobuf/issues/4311
