Update check files for -Ydelambdafy:method

Fix t8549 under -Ydelambdafy:method

the structure of Option.class generated by delambdafy:method is
slightly different. For example, lambdas declared within Option are
not emitted as nested classes, so under delambdafy:method there's no
inner class entry for anonfun classes.

The test failed because serializing a ClassTag involves serializing an
Option. Option did not have a `@SerialVersionUID`, and the classfile
generated by delambdafy:method has a different value.

The annotation is required on the parent class (Option) as well as the
subclasses (Some / None). De-serializing a Some will fail if Option
has a different SerialVersionUID.

Relates to SI-8576. We should probably have more SVUID annotations in
the library.
