Machine-specific path

I've seen the string `"-agentpath:/home/raphael/async-profiler/build/libasyncProfiler.so"` in several locations (e.g., [PS18SignBenchmark](https://github.com/cryptimeleon/benchmark/blob/master/src/jmh/java/org/cryptimeleon/benchmark/craco/sig/ps18/PS18SignBenchmark.java)). 

What is that?
