Steam Launcher sleeper script fails to recognise Steam closure after a recent Steam update (probably)

[Juppstein]

As of about 3 days ago or so the script watching Steam fails to notice when I close Steam. Since nothing has been done on the side of Kodi in regards to updates, at least from what I know, I assume something got changed in a recent Steam update. Since no error messages are generated its a bit hard for me to give you a relevant log file I guess :) But if you want me to test things out, I'm all in.

Running Kodi 19 under Ubuntu 22.04 LTS
