[lilliput-jdk17u:lilliput] RFR: 8308296: [Lilliput/JDK17] Cherry-pick: 8275415: Prepare Leak Profiler for Lilliput

[Roman Kennke]

We should cherry-pick [JDK-8275415](https://bugs.openjdk.org/browse/JDK-8275415) into Lilliput/JDK17, otherwise running leak-profiler with Lilliput would crash.

The original change applies cleanly on top of lilliput/jdk17u.

Testing:
 - [x] tier1
 - [x] jdk/jfr
