Update HidlInstrumentor.

* Instead of dlsym method HIDL_INSTRUMENTATION_FUNCTION, dlsym
  HIDL_INSTRUMENTATION_FUNCTION + insterface_name.
* This enables a single profiler library that contains the profiling
  method for all the interfaces defined within the same hidl package.

Test: mma for hardware/interface.
      local test with vts.
