stats: Adapt to new serialization of enums

Browse source 
GStreamer 1.18 changed the serialization of enums.

This patch updates gsttr-stats.py to handle the new format.

In absence of that, the script was failing like this:

```
Traceback (most recent call last):
  File "/home/ntrrgc/Apps/gstreamer/./subprojects/gst-devtools/tracer/gsttr-stats.py", line 224, in <module>
    runner.run()

    key = (_SCOPE_RELATED_TO[sv.values['related-to']] + ":" + str(s.values[sk]))
KeyError: 'thread'
```
