libobs: Adjust path for legacy browser source block

The current path would prevent the browser source from loading if OBS
itself is in the "Application Support" folder, where it might end up
when being installed via certain distribution platforms.
This adjusts the existing hack to specifically check for the obs-studio
subfolder where the old browser source library would reside.
