java/openjdk24: FreeBSD updates and fixes

- Enable and fix demangling C++ symbols in the Servicability Agent for
  FreeBSD. This fixes several issues with backtraces and looking up
  symbols when debugging or inspecting programs running in the JVM.

- Fix a performance issue when looking up committed memory size and
  number of open file handles via the OperatingSystemMXBean interface.
  This affected some large ElasticSearch clusters, but potentially also
  other large high performance systems.
