cmake build does not install {go,java}_features.proto

[jrick]

What version of protobuf and what language are you using?
Version: 29.1

What operating system (Linux, Windows, ...) and version?

Observed on both OpenBSD and Linux.

What runtime / compiler are you using (e.g., python version or gcc version)

n/a

What did you do?
Steps to reproduce the behavior:

1. build and install using cmake rather than bazel.

What did you expect to see

The same installed files as in the official zip release

What did you see instead?

Installation is missing go_features.proto and java_features.proto is installed to the wrong location.

From cmake build:

$ find . | grep .proto$
./include/google/protobuf/compiler/plugin.proto
./include/google/protobuf/any.proto
./include/google/protobuf/wrappers.proto
./include/google/protobuf/field_mask.proto
./include/google/protobuf/duration.proto
./include/google/protobuf/cpp_features.proto
./include/google/protobuf/descriptor.proto
./include/google/protobuf/timestamp.proto
./include/google/protobuf/source_context.proto
./include/google/protobuf/type.proto
./include/google/protobuf/api.proto
./include/google/protobuf/struct.proto
./include/google/protobuf/empty.proto
./include/java/core/src/main/resources/google/protobuf/java_features.proto

Compared to the extracted .zip:

$ find . | grep .proto$                                                        
./include/google/protobuf/any.proto
./include/google/protobuf/api.proto
./include/google/protobuf/compiler/plugin.proto
./include/google/protobuf/cpp_features.proto
./include/google/protobuf/descriptor.proto
./include/google/protobuf/duration.proto
./include/google/protobuf/empty.proto
./include/google/protobuf/field_mask.proto
./include/google/protobuf/go_features.proto
./include/google/protobuf/java_features.proto
