This mode of operation may or may not be desirable. Can it be made
optional?

In refkit CI testing, several selftests run tests on build artifacts
(primarily the images) produced during the previous build and only
build them if needed, i.e. they run "bitbake some-image" and that is
usually fast because the image already exists. Reusing sstate and
download dir also is important for speed.

Forcing all tests to run in a clean environment would make the overall
CI run slower.
