Run locally without "matrix" entry in .travis.yml

[agutenkunst]

I noticed that with https://github.com/PilzDE/pilz_robots/commit/a64d0a4a749b8cbe278c889bf9dc64a5d8123a85 where I switch from matrix to the job list to have proper job names removed the possibility to run locally using run_travis since this expects a "matrix" to be defined.

It seems that https://github.com/ros-industrial/industrial_ci/blob/97dc68dde37c1c94b7e8fba3b88cd0d5bcb9f2a9/industrial_ci/scripts/run_travis#L86 is really dependend on the previous format.

I found that there is (beta) some work including a "Normalized Build Config" see:

• https://docs.travis-ci.com/user/build-config-validation/
• https://github.com/travis-ci/travis-yml

I could not find out right now if there is already a CLI for creating such a "Normalized Build Config", but maybe this would be a way to handle the different ways the .travis.yml can be expressed.

I checked with https://config.travis-ci.com/explore and it seems that both Matrix Style and Job Style produce (except for the names which can only be used in Job Style) the same result.
