[lilliput-jdk17u:lilliput] RFR: 8304329: [Lilliput/JDK17] Fix DiagnoseSyncOnValueBasedClasses [v2]

[Roman Kennke]

> Some deeper testing shows that the following test is currently failing in Lilliput/JDK17:
> 
> java/net/httpclient/LineBodyHandlerTest.java
> 
> That is caused by that test using DiagnoseSyncOnValueBasedClasses, and that seems currently broken with Lilliput/JDK17 because it sets a plain prototype header on a class, where it should also set the narrow Klass* in the prototype.
> 
> Testing:
>  - [x] java/net/httpclient/LineBodyHandlerTest.java
>  - [x] tier1
