[PR] [1.19][FLINK-37100][tests] Fix `test_netty_shuffle_memory_control.sh` in CI for JDK11+ [flink]

ferenc-csaky opened a new pull request, #25956:
URL: https://github.com/apache/flink/pull/25956

   ## What is the purpose of the change
   
   Fixes the test executed by `test_netty_shuffle_memory_control.sh` that can possibly fail the CI in case Netty4 cannot reserve enough memory, hence Pekko is not able to start up.
   
   ## Brief change log
   
   - Set `io.netty.tryReflectionSetAccessible=true` for TMs, which reduces Netty4 memory footprint.
   
   ## Verifying this change
   
   Existing test should run consistently.
   
   ## Does this pull request potentially affect one of the following parts:
   
     - Dependencies (does it add or upgrade a dependency): no
     - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: no
     - The serializers: no
     - The runtime per-record code paths (performance sensitive): no
     - Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Kubernetes/Yarn, ZooKeeper: no
     - The S3 file system connector: no
   
   ## Documentation
