fix: use 3 package components for tracer instrumentation scope (TODO-39)

Changed detect_packages_from_source() from min(2, len) to min(3, len)
so com.aerospike.client.util produces prefix com.aerospike.client
instead of com.aerospike. This reduces instrumentation to the actual
source package instead of the entire organization namespace.
