Revert "binary: Generate dummy rule for relocated protobuf headers"

This reverts commit ba297413c51feab9fa43be5af56e12b79891f5fb.
The dummy rule creates an empty file. Instead of relying on header
dependency resolution, copy all protobuf output when the source
is generated in replacement of separate source/header steps.
