Reduce size of jvmti-access library

[JonasKunz]

In case the jar-size of the JVMTI-access library becomes an issue, we could evaluate reducing it by stripping the debug symbols from the binaries. According to this comment the JVM builds on linux do the same.

• We would need to ensure that hs_err_pid JVM crash files still contain functions names for the stripped binaries
• We should ship the symbols in the sources.jar and ensure that they actually work (e.g. for analyzing core dumps)

Relevant comment with suggestion on how to do it.
