Add a test runner to ignore tests on old SDKs

Generally DevSdkIgnoreRule should be used for that purpose (using rules
is preferable over replacing the test runner), however JUnit runners
inspect all methods in the test class before processing test rules. This
may cause issues if the test methods are referencing classes that do not
exist on the SDK of the device the test is run on.
