Hide misleading log entry to avoid confusion

[arielj]

Problem description

A lot of users see this in the logs when using proton and think that's the problem:

[S_API] SteamAPI_Init(): SteamAPI_IsSteamRunning() did not locate a running instance of Steam.
[S_API FAIL] SteamAPI_Init() failed

which leads into wasted time and is never an issue.

Feature description

Not sure what's the best option for this:

• we can not write that message to the disc when it happens (but it might be too costly to check all messages as they happen)
• we can write it but then ignore it when printing the info in the log modal (but it might confuse users if they actually get to the file)
• we can wait until the game closes and run some cleaning step in the log files to remove that if present (maybe this is the most user friendly method?)

another option is to NOT log the proton output, since it's useless anyway?
