We don't want any of the test devices to match the local machine's DMI
modalias. This was a major drawback in the previous test suite, hacking the
dmi modalias string was nontrivial but a wrong string could cause false
positives or negatives.
The quirks system is internal, so rather than having some fancy API we just
hook it off the environment variable that the test suite always sets. Hacky,
but a lot easier than the other options.
