Root include/CMakeList file is being installed

[francocipollone]

Parent issue #269

Summary

• <a_package>/include/CMakeFileList file is being installed. See -> installation top level maliput CMakeLists.txt in include collides maliput#507
• Also, ament_export_include_directories is being called for each include's subdirectory

This isn't correct behavior and is a blocker to correctly install debian packages.

This happens in most of the repositories.

Implementation Suggestion

• just use one ament_export_include_directories(include) in the root CMakeLists file.
