Fix CI

[pazeshun]

@k-okada This PR makes all github actions and travis pass by updating #454. However, the following concerns remain:

• All docker CI remain Expected. I'm not sure how I can fix it.
• After this PR, errors in rosdep install on travis tests against this repository will be skipped because we currently cannot avoid errors on sudo -H pip install -U fcn/chainercv/chainer (I wrote the details here and here). I feel this is OK, and github actions already skip rosdep install errors (because they keep ROSDEP_ADDITIONAL_OPTIONS as default, including -r).

Thank you As for dockerhub, That may be a different issue. I am working with #456
