Enable to build release package on i386/arm

[k-okada]

• CMAKE_SYSTEM_PROCESSOR could not returns correct host architecture on Docker container, so changed to use CMAKE_LIBRARY_ARCHITECTURE
  • https://stackoverflow.com/questions/31012297/uname-a-returning-the-same-in-docker-host-or-any-docker-container
  • Note that CMAKE_SYSTEM_PROCESSOR uses uname -p https://cmake.org/cmake/help/v3.1/variable/CMAKE_SYSTEM_PROCESSOR.html and. https://cmake.org/cmake/help/v3.1/variable/CMAKE_HOST_SYSTEM_PROCESSOR.html#variable:CMAKE_HOST_SYSTEM_PROCESSOR
• To test on i386/arm architecture on travis, change ARCH value in .travis file

yes, running arm vm is slow compared to the native architecture and I think we should add "--skip-test" option to 'generate_prerelease_script ' in future.

In .travis.yml https://github.com/Kawasaki-Robotics/khi_robot/pull/19#discussion_r288364375 :

• skip build and test for ARM containers

• • if [[ "$ARCH" == "arm"* ]]; then sed -i '/build and test/i mkdir -p $WORKSPACE/catkin_workspace/test_results; exit 0' $JOB_PATH/prerelease_build_underlay.sh; fi

What is the reason adding this? Is it for timeout of travis?
