[Lilliput/JDK17] Disable Lilliput in TestZGCWithCDS

Lilliput is not supported by ZGC, and when running with both -XX:+UseZGC and -XX:+UseCompactObjectHeaders, the latter is disabled with a warning. Unfortunately, this breaks the test TestZGCWithCDS, because it would generate a CDS archive with SerialGC - with -XX:+UseCompactObjectHeaders - and then attempts to load it with ZGC -which disables UseCompactObjectHeaders, which makes CDS archives incompatible.
