Remove out-dated and unused scripts

Nothing appears to use scripts/start-test-docker.sh, so it can be
safely removed. docker-run.sh was still referenced on our docs
page, but should soon be removed. It no longer actually provides
anything useful (i.e., any memory settings it used to have have
been removed) and is out-of-date with newer Docker setups. To
remove the burden of keeping it up to date, we should just remove.
