  scan-build-py: Force the opening in utf-8

It fails on ubuntu bionic otherwise with:
```
scan-build-py-14: Run 'scan-view /tmp/scan-build-2021-08-09-09-14-36-765350-nx9s888s' to examine bug reports.

scan-build-py-14: Please run this command again and turn on verbose mode (add '-vvvv' as argument).
```

I guess it is caused by a problem in Python 3.6
