udev doesn't work in sandboxes, notably the new Steam container runtime as found notably on the Steam Deck, and in Flatpak/Snap packages. Like SDL does, when we detect such a containerized environment, we fall back to parsing `/dev/input` directly. See smcv's comments in godotengine#76879 for details. Fixes godotengine#76879. (cherry picked from commit 788cb74)

Thanks a lot! I've given this a try on my end and it works great. 🎉
Cassette Beasts uses a bunch of weird heuristics to exclude the duplicate virtual controllers Steam creates. This sounds like a game-specific issue. |

I tested this one with Cassette Beasts on Steam Deck and it does seem to solve the issue.
Scenarios tested successfully:
It's not fully perfect as there's still the question of which of the two controllers (Xbox controller and Steam Deck builtin controller) the game decides to focus on when using both. Starting with the Xbox controller, disconnecting it, then using the Steam Deck controller will change which device the game expects to use, and then reconnecting the Xbox controller won't make it take precedence again, until changed manually in the Steam controller config. But this might be a game specific issue or a general Steam Deck quirk that may not be an engine bug.
