DMN code maint. avoid unnecessary cart.prod. test matrix

During DROOLS-3238 an abstract base test class was introduced in order to test DMN model in a KJAR containing also Drools Model file for Canonical model / executable model.

The abstract base test class BaseInterpretedVsCompiledTestCanonicalKieModule was introduced with a first PR:

https://github.com/kiegroup/drools/pull/2141/files#diff-08550863868c89e6f8ccbbc24fc7cfbaR33

However as noted in the second PR related to DROOLS-3238,

Please note that these tests don't actually verify the correct behaviour of the compiled DRL files, but they only verify the DMN model.

This inadvertently later resulted in a cartesian product matrix configuration inflation, while a single specific test would have sufficed: most of the tests which has been extended with BaseInterpretedVsCompiledTestCanonicalKieModule actually test behaviour of KieContainer on kie-server normally produced by WB/BC artifacts, which not being maven-based hardly can replicate a Canonical model / executable model artifact.
