testimage.bbclass: Allow to run tests on autobuilder's images

With the change to the new framework data store dependecy was
removed, instead a new file is generated and used in testimage.
When testing builds from the autobuilders the test data values
are from the autobuilder, including the paths.

Some tests require paths to current environment in order to run,
this commit will update such paths and fix the error of running
images donwloaded from autobuilders.
