Instead use the Cargo runner feature. The binfmt_misc approach requires running a privileged
container for setup. Not all docker setups support privileged containers so the test suite should be
more accessible with this change as no privileged container is needed.
`apt update` and `apt install` should be in the same Docker RUN statement, otherwise `apt update` will be cached and `apt install` will 404 if a package no longer exists.
