Renderer heap dumps on Linux missing module debug id.

Project Member Reported by erikc...@chromium.org, Jan 14 
Example trace + heap dump: https://crash.corp.google.com/browse?q=reportid=%27f128717fbe8a7b65%27#6

The debug IDs for the chrome modules loaded in the renderer are missing. This prevents the server from symbolizing the heap dump. Theoretically, this should work, since the browser process should be requesting the smaps file for the renderer, which should contain all the relevant info:
https://cs.chromium.org/chromium/src/services/resource_coordinator/public/cpp/memory_instrumentation/os_metrics_linux.cc?l=105

Not sure what's wrong. Requires investigation.

The version is 73.0.3642.0-trace
Is it a custom built?

Comment 2 by etienneb@google.com, Jan 14 

This is the way slow-report/memlog works.

Comment 3 by etienneb@google.com, Jan 14 

To clarify: 
  It's not a custom build.
  It's added with the trace uploader to differentiate with will crashes.

You can safely ignore the -trace suffix.

For the renderers symbolisation.
  * chrome on windows seems fine
  * chrome on mac seems fine
  * chromeos is not working
  * linux is not working
  * Android seems ok to me.
