Install opensplice on aarch64

[sloretz]

This updates the dockerfile to install libopensplice67 on arm. The package would come from http://packages.osrfoundation.org/gazebo/ubuntu-stable/dists/xenial/main/binary-arm64/Packages. It is intented to fix the failure seen in http://ci.ros2.org/job/packaging_linux-aarch64/171/console

• Packaging Linux

It seems reasonable to me; I'm fine with it as long as the CI completes.

[sloretz]

First CI will fail, looks like the platform arg to docker is arm instead of aarch64 :(

Rerunning.

@sloretz FYI we have CI versions of the packaging jobs for testing changes to the jobs (we try to avoid triggering the standard packaging jobs with non-default parameters)

Looks like this change pushed us back over the layer limit encounted building the turtlebot demo: . We could only install it if it's selected which would buy us some time, or follow up on proposals in #75

We could only install it if it's selected

That would also imply that we don't reuse the docker images when toggling the option. Therefore I would suggest to "collapse" some other line to get back under the limit as a short term workaround.

There are quite a few layers that could be collapsed. These 3 could become one.

If the first block is enough for now I would start with those.
