Make tests pass on ROS 2 (#124)

* Install the test assets to the share directory; otherwise the tests cannot locate the files to install

* Check for the systemd config file, not upstart. Upstart check left but commented-out for legacy & reference

* Add github workflows

* Modify CI to make sure tests are run

* Specify container

* Roll back to official template (https://github.com/marketplace/actions/ros-2-ci-action), explicitly set skip-tests to false

* Add CI for other supported ROS distros

* Remove Foxy

* Improve workspace fallback

* Fix build status in the README

* Set branches for CI (this repo also has ROS 1 branches we don't care about testing with the new CI)
