[Fix] Proper Check if a game is native or not

[flavioislima]

Fix how we chack isNative on GOG and Legendary.

Use the following Checklist if you have changed something on the Backend or Frontend:

• Tested the feature and it's working on a current and clean install.
• Tested the main App features and they are still working on a current and clean install. (Login, Install, Play, Uninstall, Move games, etc.)
• Created / Updated Tests (If necessary)
• Created / Updated documentation (If necessary)

The same check is also present for Legendary, could you fix it there as well?

If it is needed for both a util/generic function would be good

I sent the fix but now I will need to test, because last time I checked gameinfo.platform.install was coming undefined from legendary.

yes, we actually need to think on a better way to deal with the installed platform. there is a lot of code repetition now

Ok, things looks fine on macOS as well. Found a small bug with the filter but fixed as well
