[Bug] Steam Input controllers not usable on Linux

[vickyorlo]

Description of the issue

If Ryujinx is launched as a non-steam game via Steam, with Steam Input enabled, what usually happens is that the extra controllers Steam emulates are exposed to the application and usable. Right now, only the 'raw' underlying controller is usable. This isn't necesarily a game-breaking issue, but some people like to configure their pads in Steam and not have to worry about discrepancies from the Xbox layout. It also prevents me from using Steam Remote Play to play local coop games over the internet, because the remote players' controllers are not selectable at all.

Reproduction steps

1. Add Ryuijinx.sh or the Ryujinx executable to Steam as a non-steam game
2. Launch it with a controller connected
3. Observe if "Steam Emulated Controller" or something similar appears as a selectable gamepad in the Input menu
