insane: add test for recipe naming/class mismatches

It's not unheard of for new users to create a recipe called foo-native
that has BBCLASSEXTEND="native" instead of "inherit native". This will
result in a foo-native recipe that is actually a target recipe, and a
foo-native-native recipe for native builds.

Add a test in recipe_qa to verify that recipes called -native inherit
native, and recipes called nativesdk- inherit nativesdk.

As this behaviour is expected, add the new test to the set of tests
required to pass for Yocto Project Compatible status.
