JVM: minor, change logic of anyAnnotationDisablesIndyLambdaGeneration.kt

Do not check that non-indy-generated lambdas inherit from Lambda,
because when we enable indy lambdas by default, we're also changing the
behavior of non-indy lambdas so that they won't have the Lambda
superclass anymore (see KT-45375). Since this test was added to check
that any annotation disables indy lambda generation, just leave those
lambdas and rely on the CHECK_BYTECODE_TEXT directive to verify that
there are no LambdaMetafactory in the bytecode text.
