scripts: Add autobuilder worker test script

Add a script which can be run on new autobuilder workers to check all needed configuration
is present. Designed to be run in a repo where bitbake/oe-core are already present.

This means when we add new autobuilder workers, we can quickly test whether all the needed
funcationality to support the standard yocto project autobuilder (ie. the standard
OE-Core tests) are present.

It uses images prebuilt in a previous release to cut build/testing time.

(From OE-Core rev: c9dd81fe9c88d8d9881686e60c17e6fab4b230f1)
