ROS2 CI adjustments (#42)

* Port master build (rosws update) functionality from ros1

* Missing debug print for ros2 build

* Set REPO_NAME in ros2 build

* ros2 build: preinstall python3-rosinstall, remove gtest build

* ros2 build: increase verbosity of colcon test-result

* Remove ROS1-specific calls from ros2_build.sh and ignore tests of dependencies

ros2_build.sh
