Subject: yardstick-cleanup.sh: try to fix docker rmi failure

apex builds seem to be failing to remove the yardstick
containers

https://build.opnfv.org/ci/job/yardstick-apex-baremetal-daily-master/400/console

[yardstick-apex-baremetal-daily-master] $ /bin/bash /tmp/hudson8974425724638109512.sh
Cleaning up docker containers/images...
Docker images to remove:
REPOSITORY                   TAG                 IMAGE ID            CREATED             SIZE
opnfv/yardstick              latest              5b83d8e60fb7        6 days ago          1.84GB
Removing docker image opnfv/yardstick:latest...
Error response from daemon: No such image: opnfv/yardstick:latest
Build step 'Execute shell' marked build as failure

For some reason we can't remove the yardstick container.

Try instead to remove based on ID

Replace grep | awk with just awk.

Also fixed shellcheck warnings:
