Collect buildids&offsets to symbolicate in the backend

We had this feature in the Java profiler & async-profiler, I removed it in https://github.com/Granulate/gprofiler/pull/558 because it was not maintained and got broken.
Nowadays we have the application metadata (which already collects buildids for the main library, e.g `libjvm.so`) so we can make use of that and just add back collection of the offset when we want it again.

Tagged as a Java ticket but it's actually relevant for all.
