Run mixtool in container

Also updates mixtool to latest version which closes #1617
Mixtool was actually updated two months ago, so the dashboards are already all compliant!

For the Makefile changes, I was looking at the issue above and I wanted to test it using the build image. I noticed that it wasn't actually running in the container. This should make it easier to test in the future.
